Obviously, if I am asking for it is because a need for it arose

I am staff at several boards and in everyone of them we have needed something like this because we have features that require private forums and if you have a lot of mods it is a nightmare to take all of them out of each of those private forums.
It wouldn't be so bad if it just gave permission to the mod usergroup, but the default is to give permission to each mod individually even if I don't have them in the mod group.
So can anyone help?
