Drum track for playback?

I’ve got my score entered, ready to send out to the band. I’ll include an mp3 that they can practice with. Is there any way to include a drum track? I’ve got Cubase, so I could generate it with Groove Agent, but I’m not sure how to bring it into Dorico. Or, do I need to export all the midi from Dorico, bring it into Cubase and add the drums there?

This seems like. Perfect example of what Dorico / Cubase integration could do, but it doesn’t seem to be there (yet?).
