Widget Assistance Activity Tracker (Read 23 times)

I have a few different activity trackers on my summary page—running, biking, weights, and yoga. Each tracks time (hours) each month, and running and biking also total miles. Weights has time in hours ( duration)  and a count. So, maybe I ran 50 miles in October taking 5 hours, I weight trained 4 times taking 2 hours.

My question is can I change a tracker? My Yoga has duration and miles like running and I want it to have duration and a count like weights.

Thank you!
