Can't use CoS module in my own custom game?

I have a long running game where I use elements from other books to supplement my own custom game and wanted to use Curse of Strahd's stuff in it, but it seems like the only way I can use it is if I create a whole new game specifically for this module. Does anyone know of a way to get the info from this book (monsters etc.) into an already existing game? I tried seeing if the Compendium Selection under game settings would solve it but I haven't had luck with that either, it's not even showing up on the available list. I tried sharing the "Test" CoS game I created too but it's still not working. Is it just not possible to use any of the CoS assets in an already established game? Or am I experiencing some kind of glitch?

I think Curse of Strahd was released before the Compendium existed, so it wasn't built using that system.  I think there was mention at some point that they want to rebuild it to be integrated into the Compendium system, but that is a backlog item as far as I know.  Since you have a pro subscription, you could integrate bits of it into your ongoing game by creating a game with that module, and then use the transmogrifier to move anything from there to your active game that you want to use.

Thank you so much, this worked for me! I thought I wasn't going to be able to do it. I didn't even know about this feature, thank you for bringing it to my attention!

Transmogrifier and API are the best bits of a Pro subscription!
