Ableton BPM with RB as "master"

I'm hoping to use Rekordox to output BPM over Ableton (for soundswitch control) on a single laptop.  Is it possible to set Rekordbox as the "master" BPM provider and to change automatically as new tracks are loaded or if BPM is up/down tempo controlled in RB?  I just want RB to broadcast the current track BPM which seems like it should be possible.
