I'd love it if i could say 'follow same track from X to Y', since many of my routes go out, have a loop, then retrace part of the route. We can select points - is it hard to add a 'next add point same as previous to selected point' or something? I'd be happy to click that a few times for the overlapping section.

Maybe with an option to 'next add point same as previous to selected, then retrace to start'?
