I would like to be able to get the zones of an activity in the activity detail. If I retrieve 100 activities of an athlete and I want to know their heart rate zones, I have to make 1 request for each of the activities, so in total there are 101 requests, 1 for the 100 activities and 100 for each heart rate zone of each activity. Would it be possible to have an endpoint to get the activities in more detail (such as the zones of the activity) and thus optimize the number of calls?
