It can be... No telling what cell  is selected  and many have the
same person's name or resource name or activity designator.

HOWEVER... I could save the real contents of the selected cell and
replace it with some unused garbage (like Z43!qq7) Then, after the
sort, search  for the garbage and replace the data  and re-select...
Then I can use your find...
Perhaps a bit easier that placing the garbage in some far right
cell...
