DDJ FLX10 beat FX part selection

I would really like the ability to switch from stem selection to frequency band selection on the beat FX part selector.

What Im looking for is a controller menu option, where you can have beat fx part selection either be stems (drums, inst, vocal) or frequency band (low, mid, hi), like on the djm 750, 900, V10 and now A9. 

While I think the stems are fun to play with I would really like to be able to apply verb for example to just the lows or the highs which dont always map out to the 3 stem options.
