Currently, the options for "Automatically Add to.." is limited to the following:
Running
Cycling
Hiking
Other
Walking
Swimming
Most people will have different Gear that always falls into a sub-category, for example, a Road Bike for all "Road Cycling" activities, and a Mountain Bike for all "Mountain Biking" activities.
People will also have different gear for Trail Running vs. Treadmill Running, etc.
The current list should be expanded to include these sub-types.
Thanks!
