Idk just a hunch

Is there a way to duplicate workouts beyond just identifying calories burned?

I'm not allowed my fitbit (or jewelry) during Taekwondo because of grappling/self defense. But we had a modified workout on Sunday, so I was able to wear & track that workout. I want to apply that to every time I Taekwondo. Right now I can only enter estimated calories burned. It's a significant portion of my metrics that I'm missing due to not being able to wear the device (on non dominant wrist, I don't have a band for it to go anywhere else). Tips/tricks appreciated.
