Easy Usergroup Change

[alternity]

In our forum my admins and myself are moving users from one usergroup very frequently. This occurs in a linear fashion (we move then to usergroup 5, then 6, then 7, etc. except it's more like 24, then 5, then 2, then 17, but it's always in the same order) and I'm wondering if it's possible to add something to the postbit in order to be able to change a user's usergroup with just one click. I'd be fine sticking 25 or so <if statements in there. It's a small forum, so I'm not worried about speed. I'm guessing this would require a hack, but I'm wondering what the easiest way to do this would be.

EDIT: Really, anything that would allow admins to change user's usergroups very quickly would be work to. Basically so we don't have to all the way into user options in the admincp for each person seperately.
