Add adjustable(high) pressure for performance test's slider.

I think we need an adjustable pressure performance test in the window : Perfomance.
I think you should add a sort of infinite pascal's pressure on this little slider.
Beacause, for me per exemple, I need test real engines in the Earth sea level pressure, I can't do it beacause the slide stop at 0.10 Megapascals but the Earth sea level pressure equals 0.12 Megapascals .
I think you should add a little window and , in it , we could set a number which should go from 0 to 1000 kilopascals .
It's just a suggestion ! ;)
