Move Trim Tabs with Drive Trim Switches on Throttle

Has anyone ever wired the switches on their throttle to do the trim tabs, and not the drives? I find myself having to adjust the trim tabs much more often than the drives. Either from current, waves, or passengers shifting. Or if one side is getting smacked with waves, I'll lift it up a bit so the boat isn't digging into them.

On my stepped hull, it's most efficient to run with the drives trimmed all the way down. I do trim them up a hair sometimes, but for whatever reason I favor the switches on the dash, and almost never use the ones at my thumb.

I think the switch for the drive trim is DPST, so I do not believe I could (easily) wire what I want to do, as the trim pump needs a DPDT switch, since there are essentially multiple outputs. Valve open + Pump direction.

I don't think I'll make this change, but it might be interesting to diagram the solution.

When I have some time I'll see if I can do that. Probably make use of diodes.
 
Would suggest move some weight FWD

When my 27PC was heavy loaded it was full tucked in, regular load not and issue.

Find a way to move some weight toward the bow and then it will need drive up to compensate
