Does BaseCamp provide some type of automated way to include/insert an intended U-turn in your route? The only way I have found is to put a Waypoint at the U-turn then another Waypoint on the same road but back the way I came.
Just a waypoint should do, depending where the next waypoint is going to be. But to answer the question there is no way to insert a 'do a u turn here' symbol.
