P: 1 click Auto Levels in tone curve

Hi Adobe ,

Could we get a 1 click Auto levels in the tone curve tool please . would save so much time and effort . We could use it as an import preset .

Or we could also have the option to choose what sliders Auto Tone will use ( like in capture one ) .for exemple , I woud love to use white and black sliders but not highlight and shadow that I find too extreme for my taste .

many thanks
