there has GOT to be a way to only allow usergroup to change styles

[restless]

i've been searching everywhere... and all i can find is people telling everyone to change conditionals so certain usergroups can see things on the board. this is hugely annoying when you have to change a million different templates on every style.

can someone figure out a way to only allow a certain usergroup to change styles?

i want only my upgraded members to be able to change styles, and have everyone else use the default style. yes, because of all the usual reasons... ads, etc... but also tons of other stuff that i want to put on the board for upgraded users. i don't want to have to insert conditionals for EVERYTHING. plus, i think being able to change styles is one of the upgrade features that i want.
