Default Selected Class?

I was wondering - what determines the default class displayed on a character’s overview page? I have two classes at 70 right now, but my main class with more bosses cleared and higher percentiles is never displayed by default, so I always have to click over multiple times when I try to view individual boss logs to get my actual main.

Is there a way to designate a class as your ‘main’ on fflogs so that it gets selected by default? Not the biggest deal overall but would be nice not to have to do the extra clicks.
