Shortcut 'N': add placement of the last viapoint from the previously viewed route

[Corrado Miniati]

Hi,
In the planner, if I press "N" to start a new route after having previously planned and saved one, the map is cleared.
For instance, when planning multi-days trips, the final stop of the first day (such as a hotel) almost always coincides with the starting point for the second day, and so on.
Instead of having to reopen the first route, copy the coordinates of the last stop, and paste them as the starting point for the second day, it would be very convenient if pressing "N" triggered a prompt asking whether you would like to insert on map the last stop from the previously saved route.

Thanks
