Playing Pathfinder 1st ed and using the roll20 sheet, I see there are the 3 rows for classes. I want to go rogue 1, sorc 1, wiz 3, arcane trickster #. I can't find a way to add in an additional class row. Is it possible w/o switching the game to the community sheet? The arcane trickster is not a complicated class so I don't need the row, but it would be helpful.
