Strava is loosing out on 1000s of paying premium customers yearly not getting this done, including me =)
I've posted in this thread in 2015 and due to this is still not available I still haven't renewed my STRAVA membership. Veloviewer gets my money to get this function, not Strava.
I´ve cancelled mye premium membership due to I now have to pay VeloViewer Pro version to see the best result list.
When Strava adds these features I´ll become a Strava premium paying user again.
