Choosing Certain Styles


Well-known member
Lately, I have made a few styles for my forum, but I was wondering something. Can I make it so users can only choose certain styles?

I mean, I have:

My Default Style
My Default Style (Fluid)
My Winter Style
My Winter Style (Fluid)

I want users only to be able to choose the default or the default (fluid) and unable to choose the winter styles. Is that possible?
