Downhill biking app!?!

Hi!

Is it possible to create a downhill biking app? Or is this feature controlled by connect?

Explained:
I want an app, that don register and show elevation gain.

It works with the resort skiing app, but i would like it to register as a bike activity from the start. I noticed that there is downhill as an option in garmin connect.

Is thoose settings in the app? or inte the connect interface?
