Please add snowshoeing to Apple Watch!

Snowshoeing is a slow but vigorous activity. “Snow sports” records when you’re going 3MPH, which when snowshoeing would be really fast and essentially impossible in powder. Comparing what my Watch recorded with what MapMyRun recorded, my recent 3 hour snowshoe that burned almost 1400 calories on MMR gave me 29 minutes and <500 calories on my watch.

Also, why isn’t calorie (move) count linked solely to heart rate?
