P: LR Mobile Camera: Changing Lenses

The method of changing lenses would be simpler/faster with 3 different buttons, and not the one that I have to press/toggle through. Floating down a stream in a kayak trying to get a quick shot would be so much better not having to go through the lenses. I almost never shoot Ultra Wide, so that as a choice just slows down the process. And the shot floats away.
