Yes, but it's not straightforward and depends on what environment you're using.
Under .NET you can create something called a DebuggerTypeProxy that returns a filtered or sorted list of items
Here's a snippet of one I wrote for a project here that's still pending approval. meh
#if DEBUG
[DebuggerTypeProxy(typeof(DebugProxy))]
#endif // DEBUG
public sealed partial class Struple : DynamicObject, IDictionary<string,object>
{
#region debug proxy
#if DEBUG
sealed class DebugProxy
{
IDictionary<string,object> _outer;
internal DebugProxy(IDictionary<string,object> outer)
{
_outer = outer;
}
[DebuggerBrowsable(DebuggerBrowsableState.RootHidden)]
public KeyValuePair<string,object>[] Items {
get {
var result = new KeyValuePair<string,object>[_outer.Count];
_outer.CopyTo(result, 0);
return result;
}
}
}
#endif // DEBUG
#endregion debug proxy

Sorry, but that is just f'n scary to me. People making things way too complicated. I think.

interacting with the debugger is scary
the #defines aren't necessary, just FYI
I prefer not dragging around an extra class in release builds is all

Ok. I guess. I work in the debugger every day at various levels of complexity and I have never in my career needed to do extra code to get things done like that. I guess your situation calls for it. so be it. 
debugger has never been scary for me. knock on wood.

I just mean the visual studio live debugger integration.
it has never been particularly friendly.
using the debugger is friendly, and so are certain operations like Debug.WriteLine and Debugger.IsAttached, but to create "views" for objects beyond really simple things can often require custom code.
It's just that most people never really need to do it. The question in the OP is one that just doesn't come up that often in the real world. As those often can be, the solution is arcane. It's one of those dark corners of the debugger most people never need to touch.
How many people need to filter items in a collection or dictionary at debug time only?
Fortunately it's not a lot of code. The meat of it is in a single short method.

If you want scary - try writing your own debugger.
I did. I'm nearly bald now and I think there is a correlation.

My hat's off to you guys who do compilers, debuggers, kernel work (munchies matt i think does this), anything lower level stuff, etc.
No thank you. I have a few hairs left on my head and would like to keep them if possible.

The debugger I wrote was a companion to the script language compiler I also wrote. It wasn't just merely a script language though - it compiled to native machine code and it was pretty fast. Writing those was some of the most fun I have ever had programming. It was also very tricky, hence the lack of hair. Sometimes, when I am feeling particularly masochistic, I think about what I would do differently. Then I remind myself that it's not my problem any more.

Same as what Guy said or you can also use Quick Watch and it is easier to navigate to what you want to see there.
Just right click on a variable name and select Quick Watch while in debug break-point mode. I use this a lot.

I use Oz Code debugger extension - I love all the things it does. It even predicts future events that can cause bad things to happen and warns you before your debugging pointer gets there....
A human being should be able to change a diaper, plan an invasion, butcher a hog, navigate a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

What are you listening to while you code?
TOBACCO - Dimensional Hum - YouTube[^]
This album, right now. Tomorrow, something different

I like Dance / EDM very very low in volume.

EDM is an insanely popular choice among the devs I know.
I listen to TOBACCO a lot, they're sort of EDM'ish but more ambient than dance usually. Kind of a weird mix. And they're off beat a lot so you have to be good with that. Some people find that jarring

Currently, the sweet sound of silence!
I find concept albums to be the best, especially double albums. A short list, off the top of my head and without providing links in no specific order: (sorry, too busy now!)
0: Pink Floyd - The Wall
1: Neal Morse Band - The Similitude of a Dream
2: Spock's Beard - Snow
3: Dream Theater - Scenes From a Memory
4: Queensryche - Operation Mindcrime I and II
5: Symphony X - V (The New Mythology)
I usually only listen to music while coding after business hours when I'm less apt to be interrupted.

Have you checked out Steven Wilson's solo stuff, particularly 'The Raven That Refused to Sing (and Other Stories)'? Good stuff! I saw him a few months ago in Pensacola in a club...small audience, but they put on an amazing show.

I've listened to some of his solo stuff, but like him with PT better.
Would love to see him/them in person. If I would have known they were playing in Pensacola I would have come over, I'm in Jax!
I do all my own stunts, but never intentionally!

Dream Theater will be there in a few weeks. (27th) I just got back from seeing them in Chicago. The second half of the show is 'Scenes from a Memory' in it's entirety.
BTW, I'm about 90 miles west of Tallahassee...most of my customers are in FL.

Check out The Art of Noise - The Seduction of Claude Debussy
It's an operatic biography laid out in scenes.
It's also a really great meld of improvisational electronic and classical music.

If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

i'm down with the message, but the genre isn't my cup of tea.
