HIIT

Anyone having sulotions for how to register HIIT / Hyrox / Crossfit workouts including cardio exercises? I have a Felix 7 and are far from satisfied regarding HIIT workout tracking. 

- Register running/tredmill/RowErg/SkiErg as distance? Garmin somehow does not have distance as an option?!?

- Register SkiErg/RowErg as exercise? Garmin does not have it listed as an option?!?

- Have you guys used any app for tracking rowing/skii?
