BB Sync, Metronome Apps, and Auto Tempo Changes

Hi all –

I’m connected successfully via MIDI/BT Sync with my BeatBuddy.

I utilize Frozen Ape’s Tempo App - - because I can set up practice sessions and automate tempo changes for improvement.

Any ideas if there’s a way to slave BB or create practice regimens with auto tempo change per bars/time allotment?

My use case was to figure out a way to drive BB’s tempo from my Metronome app – but I’m not finding a way to do that in all my searches.
