Record treadmill decline data

I just recently bought a new treadmill (Nordictrack c1750) that has a decline ability, and I have been using it as well as incline. I use Runcline which is awesome and allows me to record my incline and decline data, but zwift doesn’t record decline. It would be sweet if this could be added as I would like to track my decline data in strava and powercenter, runalyze.

Thanks apologies if this has been requested before, I did a quick search and didn’t see anything.


Loving zwift running.
