Adding all monsters from Compedium into a game

I'm a GM who intends to have a CO-DM at my table.  To make things easier for them, I wanted to put all the monsters from my compendium into the game like they have in modules; however, I can't find a way to just drop all the monsters from a book into the game.  I know when you create a game you can add a module like Xanathar's Guide to create a game with all the monsters and a page with them all on there, so can I create a game that contains multiple of those without having to individually drag/drop every token from the compendium? Thank you

Hi William! If you had a Pro subscription, you could get a good head start by using the transmogrifier to move one of those pages into your current game. Otherwise it is drag and drop. On the other hand, if you give another player gm privileges, this includes access to any compendiums you have shared in the game; they can drag and drop assets for themselves.
