How would one restrict a usergroup to one forum style?

[w00ttastic]

I want to punish misbehaving users by restricting them to an annoying/lame forum skin, and I thought there was an option in the Usergroup Manager to restrict changing forum styles. I looked through it just now and there doesn't appear to be one. Is this a built-in option or am I going to have to rely on creativity that I sadly lack?
