Not automatically. You could do it with a lot of effort via selection
and the programmable filter and the spreadsheet view.

The process would be:

Split the view top to bottom and make a spreadsheet view. Show the
data's selected point values in the spreadsheet view.

Insert a programmable filter, make it shallow copy through the point
and cell associated attribute data.

Split the 3D view again, now right to left, and make the original data
visible in one view and the filter's output in the other. Link the
cameras.

Select a vertex in the original. It's index and coordinates will be
shown in the spreadsheet view.

At a line to the end of the python filters program and change that
particular point's coordinates in the output data.

Repeat the last two steps, adding to the program each time.
