POTENTIOMETER PHISICAL STOPS

Would it be possible to add stop to the limits of the potentiometers? customizable of course,  by default with limits by setup without.

As I understand currently potentiometer has stops.
What exactly do you propose?

No, it not has stop, you can do the comple rotation and this is complicate to use sometimes.

Well.. the stops are not like physical, it stops at the initial and final marks, but if you keep moving much more then it keeps moving.

That is what I am asking, add phisical stops to the potentiometers.
