hi Kasey, I think the proof approval workflow used will show up if you just make a column for the "workflow template"?
I don't use proof approvals in my system (I just looked and we have 2) so I'm not the best person to comment past this. But if I had to do something quick and dirty I would pull up a proof approval report and filter for everywhere the workflow template is not blank, and then sort it by that (or maybe even group it if that's available) to figure out which ones are being used. It's a bit manual to then deduce which ones are not being used (maybe someone can come up with an exists statement for that), but if it's a one-time thing, at least you can get that done for this time.
