This is already possible. Set Tempo Mode to “MIDI” and configure your DAW to output MIDI clock over USB.
You can also use Emote as a plug-in, set Tempo Mode to “DAW”, and the H9000 will follow the tempo of your DAW Session. https://cdn.eventideaudio.com/manuals/h9000/2.2.11/content/emote/plugin.html#daw-tempo-sync
