Well, what you can do is: - Become a Pro User - Create your own sheet (on the basis of the two given sheets) - Make the sheet toggle between two (or more) sheets (as some sheet authors do to create a PC and a NPC sheet within the same sheet) But this will result in costs (both money to become a Pro User and time to make the sheets compatible, as two Pathfinder sheets will likely have some same attribute names so that merging them won't be that easy).
