Rekordbox related track options

Hi i just installed RB 5.1 and saw the new options for the related tracks function. So my suggestion is: how about to select specific genre or color for the results? At this time i can only select same or not. That would help me for example to find for the track i want, all the acapella's they match with it by selecting for the results acapella as the genre. I still can do it, but every time i have to change the genre in the track i want to found a match.
