There are thousands of sports that are not listed, including some of the most popular ones. And that's becuase there is no reason for having them listed. You can track practically any sport, with some of the available profiles, and on most Garmin devices, you can also define your own custom activity types, so nothing can prevent you from adding bowling too. Or just recording it as Cardio, or another indoor sport.
From the point of view of burned Calories (if that was your concern), the type of the sport you chose, is completely unimportant, since the Calories burned are calculated with the help of your current HR, the HR Variability, and the average resting HR from that day.
I want to buy the newest Garmin Epix I was hoping it had ten pin bowling as one of the sports but I guess it's not that means I'll have to manually put in tenpin bowling for cardio
