Hey Titus, I believe this is entirely possible. Create a temporary campaign. Drag in all of the creatures you are likely to want to use from the MM. Highlight each one in turn by selecting them and pressing "Z" to get the preview. Right-click the preview to download it to your hard drive Repeat for each one. Upload all of these into your personal art library (any game--doesn't matter.) Open your module game Open a character sheet you wish to update with new art. Click the edit button. Delete the old token, drag the new token from your art library onto the token art section. Press the "Apply Token Defaults" button. This will update the default token, and all tokens on every page in the campaign. It looks like a lot of steps, but depending on the size of the module, may not take too much time. Work carefully, this makes global changes in your game.
