Moderate Specific Forums Based on Usergroup

[Crxssfade]

Hey guys, I've done a quick search but I can't seem to find what I'm after.
Basically, I'm wanting to assign moderators to a specific forum based on their usergroup. I understand there is the "Is super moderator" in the usergroup options but that will allow them to moderate and ban throughout the whole forum.

What I'm after is something like how you assign an individual moderator to a forum, but in usergroup form.

I'll provide an example. Say for this forum, the "vB4 General Discussions", and there is a usergroup named "vB4 Moderators" are you able to make it so when someone is added to the usergroup they are assigned as a mod of this forum and when removed their mod abilities are also removed?

If there's a mod for it that'd be great, any help would be great really.
I hope I make sense :S

Thanks!
