Adding a controller to OEM air compressor?

[19CHEVYburb]

I was curious if anyone has tried to add a controller or something to control air pressure on the rear shocks. I know most people delete them but I found Bilstein 5100 in the front and keep rear air shocks it rides good. Also when I tow my enclosed trailer the rear air shocks really level the truck out. So the issue I've had is when I am un hooking my trailer, because the increased pressure from the weight they raise the truck pretty high to where it's annoying at how much work it can be to put a trailer on or take off.

Is your rig off when you unhook it? I’m trying to picture what’s happening. Could your ball be too high? I use a 2” drop hitch on my lowered rig so I haven’t run into this. I don’t know of any external controller for the rear self leveling shocks but someone else may.
