Route Planner: plan route to or through existing waypoints again (round trip)

In route planner it would be helpful if I could easier create a new waypoint next to an existing one.

At the moment when planning a route that should pass a geo point multiple times (or return to the start point), always the existing waypoint gets selected. I could not add another waypoint near the existing one.

My workaround is to add a waypoint somewhere else and the moving the new waypoint next to the existing one.

Same problem is with planning a round trip, that should start and end at the same place.

It would be great if I could easily plan a new waypoint next to a existing one.
