Identify Source of Manual Move Operation

Hi all,

Scenario:
A user selects a range of cells, then manually moves it (by dragging its border) to a new location.

Question:
Can I identify what the source range was so I can further manipulate those cells with more vba code.

Note: I also have to manipulate the destination cells, but identifying them is easy because they are still selected following the move operation.

Any help is greatly appreciated,
Thanks,
