The right shift will normally fill with the sign bit, which is the left most bit. There is no "special" bit when doing a left shift, hence it is always zero fill.

it can be done... << can be made as filling with Least Significant Bit and then <<< can be operated as zero fill left shift.. but this had not been done,,, this is the question...

It cannot be done, because most hardware does not offer the feature. And furthermore, there is no real need for it. The designers of computers and languages did not provide this feature for the reason that there is no logical reason for it.
