We have gotten similar requests, we do not plan on doing anything like this very soon, though we may explore the possibility when we look into one shot parts, as the issues seem linked.
On the bright side, since you mention you have a BeatBuddy, by using the upcoming Autopilot mode, you could plan out your song on the BeatBuddy Manager and then use the BeatBuddy MIDI part change capability to control the Aeros part changes as you need them. So there’s good news there! That is also in the works and is more likely to come sooner than an Aeros update on the matter.
Thank you for your feedback!
