This has been asked before, but it seems like nothing is planned for this request. During a ride, I climb a hill. After the ride, I can zoom in to the interval for the climb, but it does not show me the average power. It would be a very valuable feature to show average statistics for a zoomed interval. By the way, Strava has this feature which is used by many cyclists.
In theory, one can use the lap function to mark the climb as a lap and study the lap statistics. But one does not always know when a climb is coming up, or sometimes we change the route as we go.
