Maybe one way to do this is to make the feelers act as keyboard shortcut or even as joystick. Then open AOG in Sim and let shortcuts steer the tractor.
One of the threads mentioning shortcuts :
Customizable keyboard shortcut.
EDIT:
Correct as potatofarmer says in next post, but to follow any row (planted with a drawn machine without gps on it) would also be nice:
Another way to do this with feelers (or camera) is to open normal AOG and use “Drive” if there were shortcuts for R and L there.
And If you still have the gps on the tractor you can “paint” the worked area correctly.
