Linking Multiple Groups to one Mod Thread

Perhaps there is already a way to do this, but I haven't been able to find it. Our mod (Movie Battles II) has a pretty vibrant mapping community that maps specifically for our mod. A lot of these third party mappers got together and formed the Community Map Pack, which is just a way for them to distribute their work together. Now, they've formed a group on ModDB, and I'd like to allow them to post addons to our mod. I don't want to add them to the development group, because they're not officially associated with the mod's development team.

Is there a way to allow the independent CMP Team group to post addons to the Movie Battles II mod without adding them to the development team?

Hm, I don't think theres a way to do this at the moment, which is a bit of a downside of the linking system. Maybe INtense will jump in here and give us an answer

Thank you, to whoever on the ModDB staff linked it manually.
