Render distance slider memorized preset

Hello guys.
Recent videos from Matti made lots of people including me constantly change their render distance for different engagements.
If you're not familiar, 500 meters is minimum and is really all you need for infantry combat. It also gives you much better perfomance.
If you're flying, 1500 is optimal.
Problem is, there isnt shortcut for it, and you have to manually tamper with the slider everytime you want to change it.

I could only hope if its possible for you to create a presets for such things, so by the press of lets say "numpad 1" I get renderdistance set to 500 etc.
Thanks, vsae out.
