I think there are a lot of different ways to go about achieving your goal. The simplest one to my mind is that you can open a collection or setlist on the library screen to view its songs, then long press and start selecting all of the songs you want in the new collection/setlist. Once you've selected them all, you can use "Create Setlist from Songs" option in the overflow menu (or collection if you want that). If there are easy filters to apply, you can use those filters on the library screen or in the setlist editor to limit the song list before selecting.

itsme - I can certainly look into saving the last used filter on the group editor screen and restoring it. I think I would only want to save it for the current session of MobileSheetsPro though. If you restarted the application at a later time, would you still want that filter applied when you go to edit something? I would think not, as it could be tedious or cause confusion if you always have to clear out old filters.
