Hi Im considering to buy a subscription (Plus or Pro). I'm a player, not a gm. In 2 different games. None of the 2 games are well supported by existing sheets (Earthdawn and Dark Ages). Can I create 2 custom sheets, with API code to support them and provide them to my 2 GMs? I'm guessing no based on what I read. But please explain to me what is the shortest route to achieve that.
