[Framers] Is is possible to change how Frame increments numbering?

[Lin Sims]

Or, rather, lettering? It turns out that when you use Snagit to create
lettered callouts, it goes from Z to AA to BB. Frame, on the other hand,
goes from Z to AA to AB! For now my workaround is to manually type it in,
and eventually things will change so I don't have so many callouts on a
screenshot, but for now .... for now!
