Making the infractions and banning systems capable of ban a user permision
 

First of all, sorry for my crappy English.
I'm trying to do my best whit it.

There's only two options: to ban or wait to ban. XD
Two big and powerful systems, and the final solution is the absolutly ban.

I don't want to do that.
I want to be able to give my mods the capacity to "ban" an ability of an user for a period of time.
Turn a user incapable of use an avatar or signature.
Turn a user incapable of access a forum.
Little ban options.
If an user got 10 infraction points, he got removed his ability to use an avatar. If got 20, the ability to enter a certain list of forums. Etcetera.

Ok, I can do that. Go to the admincp, create a new group, and make this unable to do the banned abilities. Next go to the ban system, per example, and ban him to that group.
But there's the problem: Maybe you want a user to be banned of "avatar" and "reputation" abilities. You need to create another group!
And its the same with all the combinations.

If only I'm be able to create a group who only turn off some ability, and let the others be the same as the primary group options...it'll be perfect.
With this I can make various effects for points of infractions...and the ban system will "ban" for an time-lapse a user to do some thing.

Its there something like this?
If not....its possible to do it by other way?

Extra: One little question...its possible to make an scheduled task who erase an avatar of a member who don't turn online in a month?
Simply turn off his custom avatar.

Here comes a bump! ^ ^

Please, at least tell me if its impossible or very very hard to obtain.

And if you could answer my final question....I really need something like this to get back the avatars of the gallery, because I'm using a modified versión of the Unique Avatar mod.
