Associating isometric tokens to monsters from the official supplements

Hi, I am trying to develop some isometric maps for my D&D 5e campaign. However, before buying additional tokens/maps in the marketplace, I was wondering whether I would be able (via a macro, API, etc.) to associate any new tokens with the "classic" monsters that you can find in the Monster Manual, Mordenkainen's tome of foes etc. In other words: is there a way to create a custom token that replaces the original ones, or even better, to make a choice between different tokens every time you select a monster from the compendium? Otherwise, I think this would be a great new function, particularly to woo isometric enthusiasts like myself!!!! Thanks a lot for your help!!!

You can change the token used for a particular character (Monster, PC, whatever) in a given game using TokenMod.  It would look something like this, with the token selected: !token-mod {{ --set represents|"?{Monster name}" }} Followed by setting it up the way you want it, something like: !token-mod {{ --set bar1_link|hp bar2_link|ac bar1|@{selected|hp} defaulttoken }} etc.

Just for anyone else reading this, it can be done manually as well. Any time you drag a compendium creature into your campaign, it becomes the default instance of that sheet for subsequent compendium drags. If you drag in a goblin, change the token image, maybe ad a few token abilities as well, and save it as default, that is a goblin in your game. Even if you drag in a fresh goblin from the Compendium, it will be placed on the table as your local default goblin. You would need to delete your local goblin to get a "pure" Compendium goblin again.
