File structure for content pack add-on?

Hey guys,

I’m interested in making some smaller add-ons for pre-existing content I have on the marketplace. I’d like the add-on to merge with the original pack (same content folder, different subfolders). Mostly, I’d need to do this in order to reference a Material Parameter Collection I have in the original pack (so that all add-ons are working in conjunction with the original).

Just curious if anyone has done something like this before. Would it work? Would Epic even approve it?
