XF 1.4 Seeing What Styles are in Use

I have several styles available on my forum and I am wanting to know which ones are the most popular or not being used at all. I have noticed on other forum software it is possible to show what style a given user has selected (and presumably gives admins the ability to see the usage stats in the adminCP). Is this possible on XF?

Reason: I originally added several styles (5 of them) to give options to the users but quickly found out keeping them up-to-date was not something I wanted to spend a lot of time doing. I'm wanting to narrow it down to two styles but I don't want to get rid of one that is popular.
