This is the description for categorizing the exercises in the latest update from the Microsoft blog entry that also announced the music controls and the activity reminder:
I was able to add the custom exercise labels from the Microsoft Health app. Unfortunately, there doesn't seem to be any way to recategorize a workout after the workout is uploaded to the dashboard. I'm also not seeing the workouts grouped by type when viewing the summaries and observations from the dashboard. Has anyone figured this out, or have they not fully implemented the change in the dashboard yet?
Now, it’s easier to track your duration, calorie burn, and heart rate for your favorite exercises when you use the Exercise Tile. Select popular options, like yoga or weightlifting, or name your own. When you review your exercise sessions in the Microsoft Health app or Web Dashboard, your summaries and observations will be grouped by exercise type for better insights into your performance.
