Complex yet small regulator with multiple preset options possible?

[Sear]

Hey guys. I'm using a heavy paintball AT gun powered by HPA ranging from 9-14 bar (depending on the shooting distance). It does currently have a standard regulator with two gauges on the scuba bottle. But anytime shooting distance suddenly changes (which happens often), I need to adjust the pressure turning the valve, empty the chamber, fire a blank, check the pressure, do it again, and only then I can load and finally shoot. It is tedious and takes a precious time in the battle.

Is there any smart and compact way (there ain't much free space in the 37 mm PAK left), how to let 16 bar from the bottle and using 3 smaller (inline?) regulators or one "smart one" (in case such thing exists) to quickly select one of the three pre-defined pressures the way that the system releases the extra pressure from air reservoir in case I go from higher pressure to lower?

It sounds like you just need a venting regulator if I'm reading correctly.

Good advise! I didn't know such things exist. So far I had an idea with two to three regulators set to different pressures and regular safety valves behind them.
