2 levels of sorting needed! Much needed

I am a total rekordbox user and make my style accustomed to the tools available. And what would help me greatly is

A 2 level sorting of like multiple colours and multiple ratings:
Generating a playlist sorted by, x colour rating 1 (multiple tracks), y colour rating 1 (multiple tracks), colour y rating 2 (multiple tracks).... Etc

Will reduce the selection process time greatly.

If such a thing exists already in rekordbox or around it plz advise
