Hey, guys. I apologize if a topic about this has already been made; I wasn't able to find one after some searching.

When transposing songs in the iReal Book app, let's say, Harlem Nocturne, from A Minor down a minor third, most people would be able to understand it as F# Minor. In the app, on the other hand, it's transposed to Gb minor, which goes deep into the double-flat range. It's no major problem, but just a slight inconvenience to have to think of it the other way in such an unfamiliar key. Is there any way to fix this and transpose these songs enharmonically from Gb to F# instead?

Thanks in advance.
