I had the same thoughts already about this. Good suggestion and really hope this makes it in the game!
Or if you actually have lit the different mode shots by shooting them x times you could stack 1 other planet mode along.
Or you could stack as long as you are playing at least a mode from the shot you just made. And once that shot has no more modes to be played, you must start the other modes in one of the other shots.
But totally agree the left ramp and right small loop exploit should be covered.
