Handcycle workout

I have an Apple Watch series 4 and I am in a wheelchair, the reason i selected the Apple Watch versus other wearable trackers is Apple has developed the watch for wheelchair users. Using a wheelchair definitely has different push options and the Apple Watch can track my activity. However, my main form of exercise is using a Hand cycle, whether it is indoors when I am using it on a trainer or out doors on the bike paths. There needs to be an option for hand cycling as an available workout. How do I ask to have an activity created for hand cycling?
