Is there a way to do a reverse route on a route segment? Example, we're taking an RV to Stone Mt, GA. The park has three routes in - one of which is not RV friendly. I can route my preferred entrance into the park, but in trying to exit, S&T will use a non-preferred exit. Can one reverse the preferred entrance route so exiting is the same route without having to mess with the avoid area feature to cancel any attempts by S&T to route out another way?
