Transport from both Ableton and AR?

I have OB all setup to where everything is pretty much in sync and the audio sounds good. Ableton sends start/stop and clock to Rytm (through OB) which sends to Octatrack which sends to everything else in the studio. Works good. My question is- is there some way to also/instead use start/stop from Rytm to go to Ableton? I feel like I had it working like this the other day but can’t remember the settings.
