What does “extend route”?
I could neither find it in the docu nor understand it by experimenting.
The gpx dialogue is indeed more complicated.
That makes it questionable, to try to change the route during import - at least for the gpx-dialogue.
It is difficult enough to replicate the original version as close as possible.
Despite my above proposal I am not a fan of changing the route directly during import.
Although it saves a few clicks, I think it would be clearer and more predictable to separate things into single steps.
- Import route (this thread)
- Modify route Waypoint as route start / delete previous waypoints
- Navigate Navigation: rerouting options
