can different characters use different UIs?

This question may be tiring, but the search filtered out the word "different" so I couldn't find what I was looking for.

I used to use custom UIs a few months ago, but it kept getting frustrating having to update everything or change everything when Sony updated their UIs. Not to mention my wife on her account never was a really big fan of having to use the UIs I was using.

Used to be, I believe all characters had to use the same UI since you had to create an INI file in the EQ directory and that made every character use a particular UI. Is it still like that? Can we get around that?
