After needing the modular weapon functionality and not finding it on other fab related assets, I decided to do it myself.
Just add the AWC actor component on the character or weapon and you good to go.
Version 1.3 is up for the AWC.
You can check it out here - there's also a demo: https://www.fab.com/listings/3e7b8d87-418a-414f-bcb8-9d33ef6d16da

guess I'll have to hit up support again ๐
. Thanks for taking the time though!
