Power trim Yamaha 2003 225hp 4 stroke

Is there a way that I can wire the power trim switch that is on the side of the engine to be active when the battery switch is in the off position? (The bilge pump is always active even with battery switch off.) I could do this with my previous mercury sterndrive.

I trailer my boat; it is a pain to have to climb back into the boat to switch the batteries off after I rinse out the engine and raise the engine up for future trailering.

Thank you for any advise on this subject
