Home-brew Campaign with Modules. How to use parts of Marketplace Modules in one game

I am building a home-brew campaign that will used parts of the following modules in one game:  Tyranny of Dragons WaterDeep Dragon Heist Baldur's Gate into Avernus Is there a way I can load the modules to have access to items within each modules? The players will not be using character sheets on the Roll20 platform.  Thank you for your time  Christopher

The only way I know to mix them all in one campaign requires a pro subscription for access to the transmogrifier.  You would create a game with each module.  Then you would create the game you want to mix them in, and pull in anything you want/need from the 3 module specific games by way of the transmogrifier.

It depends on what you want to merge together. The easiest way is to use the transmogrifier (pro feature) to move anything you want between games you created. Another method but more work involved is to use the character vault to move specific pieces that you attach to blank character sheets temporarily. The most labor intensive way is to just cut and paste them from one game into another. There are limitations on every method but the pro feature gives you the easiest way.

Thanks, I have a Pro Sub. I just did not want to purchase a bunch of modules if I could not mix and match things like maps and tokens.
