You can always use the “skip next waypoint” feature (cklick navigation panel)
Note the rerouting options are:
- Nearest point on route - this is not the (numbered) waypoint!
- Nearest waypoint - this is the numbered waypoint
- Next unvisited waypoint.
Here is explained why - especially in roundtrips - rerouting could change the planned route if you use anything else than “Next unvisited waypoint”.
