Hey there, unfortunately, this is a big rework of how the Aeros logic works and we cannot easily allow the definition of a new custom loop point.
We are toying with the idea of allowing a user to select whether the loop point is fixed at a starting point or if it always resets when a longer track is recorded (how it works now) but this is probably the furthest we would go.
As far as the organization of songs, you can check out a similar request here, although it also has a fate of likely being too complicated to implement ever.
Thanks for the request!
