Feature Request: Filter for Custom Workouts on Stats page

In trying to compare the amounts of cardio, HIIT, Pilates, strength, toning, etc.; muscle foci; and levels of difficulty, etc. between various programs/challenges using the infographs on the Stats page, unfortunately, it is imposible to figure this out for FB workouts only b/c there seems to be no way to filter out Custom Workouts.

While the "Training Type Minutes" chart shows # of workouts in 2 different colors for FB vs. custom workouts, it doesn't separate the # of minutes (which would be more helpful to see separately than the # of workouts, imo).

Specifically, it would be really great to filter for FB workout vs. custom workout in these particular infographs:

- Workout Difficulty Minutes

- Body Focus Type Percentage By Minutes

- Training Type Minutes

That way, one could include/exclude either workout type to get a clear picture of both the programs/challenges and other FB workouts done and one's custom workouts.

It would be really helpful to be able to see this for figuring out what program/challenge is a good fit, as well as to see both the percentage of cardio/HIIT vs. strength/toning, etc. that has been successful personally as well as to quickly, visually compare programs/challenges to each other.
