Created a new game and want to add maps from other books to this game

Hello,  So, I created a game and I want to pull maps from other books that I have in my compendium into this game. Is this possible?  For example, I created a game called The Fall of a Nation - this is homebrew. And I want to pull maps from books I own in Roll20 like Explorer's Guide to Wildmount, Sunless Citidel, and Xanathar's Guide to Everything into one game. If this is possible, could someone please explain the process. Thank you.

The ability to freely move pages, characters, handouts and more between campaigns is a Pro feature, and uses the Transmogrifier tool. It's probably the second best feature of the subscription level (after the API). It's much harder at other sub levels, and can really only be accomplished by downloading map images and re-uploading them, or attaching them to characters as tokens and moving them around using the Character Vault.

Ah, ok. So if I went Pro, I would be able to do what I want then. Ok, until then I will try the token import you talked about.  Thank you.
