Rover - go Home, Good boy - Smart RTL

Hi, Im looking for a nice way to send the mower home after mowing one of 3 paddocks.

The mower lives in the shed. I’d like to flick the RTL switch and have the mower head home, but not through the fences or gate.

I can load a specific " go home from paddock 1 or 2 or 3 " mission, but it sucks loading a whole new mission, just to go home. Note - the gate is always closed due to stock, so the mower needs to wait until an all clear command of some kind before driving through it. Its a clear run from WP1 to WP2 etc

Any help or pointers appreciated.
