Maybe set a destination point so you can get your pokefarmer to travel back to your farm?
or set a route to your farming spot with a variable speed - i.e car for traveling to the area and then revert to walk, jog and bike.
could maybe even set a return route? especially if you know of any nice mining spots nearby. it would look a bit more realistic perhaps?
Bump, I would also like to see a feature similar to this. I have a few nests where I live that I'd like my bot to go to whenever it gets off track without needing to stop and teleport over.
