Xdj-rr tagist rekordbox

Why can't pressing tag list on xdj-rr display a list of tagged tracks from rekordbox just as it can tagged tracks on usb or display playlists? Seems a no brainer. I mean the tag function on the unit works to tag and untag tracks in rekordbox fine... It would really help when compiling sets on the fly when meandering through different playlists or remembering requests to drop in later on. Very annoying it doesn't work as one would think it should....
