Browser Tree Midi Mapping / Playlist scrolling

Would be usefull to have a seperate midi mapping option for browser tree and to browse playlist, eg one rotary knob could be mapped to scroll through the playlist folders and tree and another rotary knob mapped to scroll through the actual tracks in the playlist.  

Constantly clicking to switch  between them, could be simplified and it alot quicker when navigating especially when doing short quick mixes.Traktor has this option and it was very use full and made browsing and searching a lot quicker.

Especially if you use a third party add on controller for effects and searching.
