Default TSS Calculation choice for Swim Workouts
For swim workouts that have full HR data, the hrTSS seems to be a much better measure of workout intensity / fatigue than sTSS (swim TSS).
The ability to set swim workouts to either hrTSS or sTSS as a default would allow users to chose what works best for them, and not have to remember to adjust / change after the workout.
Currently, ALL Swim workouts default to sTSS.
I see this also shows up for trail running as well.

As a coach, I would be happy if I could set the TSS values for all of my athletes' swimming training sessions to hrTSS by default. Currently, Trainingpeaks only provides sTSS.
