I just want this. Keep it simple.
So maybe this would be a simple enough change ...
1. Keep this part the same...
Press and hold either track button - Simulator acts the way it does now
Bank and rate depend on how long you hold it
When you let go it rolls itself back to wings level
2. And add this tiny change...
Tap Track Left - get a Standard rate turn to the left
Then tap Track Right - roll out of the turn
