Default Line lock for Ebrake

2012 F350 Longbed, 4 door, dually 4x4. Lifted with 37's. Roughly about 7000 lbs. Ford's E-brake pads are known to be garbage and whenI'm pulling a 7000 lbs boat, the holding power for these brakes on a ramp are a joke, even with new pads.
Wondering if anyone has installed a line lock on the rear brakes for use on a ramp. I'd go with an on/off instead of the momentary switch (like in a race car) and would keep the normal E-brakes operational for daily use. Basically, the lock would only be in use for 3-5 minutes while loading solo at the ramp. (full disclosure: new rotors, new pads, new cable, adjusted properly. It holds on level ground, but just not with the truck/trailer on the ramp)

Has anyone tried this before?

We had a hydraulic brake lock on some of the wreckers I used to drive. Pull a knob on the dash that connected by cable to a check valve. Then push hard on the brake. To release just push the knob in. They worked pretty good. If you have rear disc brakes even better as drum brakes never held as good backing down. I think they were called Micro Locks. A line lock with a toggle switch should work fine.

A little OT but 2019 GMC 3500 is reported to have this feature.
