I would love to have the feature to add a Strava segment to my route, like we can currently do with a waypoint. This would definitely make planning routes based on segments much easier.
At the moment I can display the segments in the route planner, but unfortunately I can't add them directly to my route. I always have to set my waypoints accordingly and make sure that the route takes the right turns, as the segment is not always the most popular route. On most other route planning platforms with segments this is already possible and I would like to see this feature in Strava as well to use the great Strava segments more efficiently.
