Hey! Yes we do not allow batch requests as per the Forum Rules, you can see more info about making requests here.
This doesn’t seem as useful as the current logic and we likely will not add it in. The way the Aeros works is if you have Sync length on, and your original recording is even, all subsequent recordings in that song will always be even.
Undoing a track and re-recording over it is the same premise and satiates the need to delete tracks. Deleting tracks is not so straightforward and we will not be allowing this any time soon if ever. You can already delete a part by pressing the song part icon on the touchscreen, you can only delete the current last part. Deleting is not undoable.
You don’t have to actually request this as it is part of our original promise of features, it is coming soon however.
For this reason I will be moving this to the general Aeros folder, thanks.
You can find the full logs in our manual
