Documentation on the import function / naming conventions?

[falcon2001]

Having a bit of a pain with a few different things in regards to importing card art, and as far as I can tell, this isn't actually in any of the documentation I could find either.

There's two types of cards I'm running into issues with:

• On tokens, how do you specify the token name/set? As in Innistrad horror token vs Ice Age horror token or whatever.
• On split images (Ravnica block or otherwise) how do you name them appropriately that the card art gets imported?
• As a note for folks that hadn't found this yet, I did find that transforming cards (for example, Bushi Tenderfoot) needed to be two separate card images, one for each state.

Thanks! Really enjoying Forge, just couldn't figure this one out.
