I have a large data sheet with formula referencing cells on 'WorkSheet' row
35. I would to change them all to reference the same column number on row
36. (ie change all references to U35 to U36, change all references to B35 to
B36)

I tried doing this using find/replace using a wildcard as follows:
Find: WorkSheet!?35
Replace: WorkSheet!?36

Doesn't work. Can I use the wildcard this way such that it finds a
character but leaves it unaltered during the replace?
