Elliptical - ALMOST!

I’m unable to ride since breaking my hip so I quickly attached a Garmin Bike Speed Sensor onto my elliptical trainer(see attached picture) tp try for striding, but Zwift wouldn’t recognize that sensor within the running sensor setup section. However, the sensor is recognized in the riding sensor setup section and after choosing the “unknown” trainer and selecting the largest wheel size, my bike avatar starting moving at 6-8 MPH which is a good running pace! Is there anyway that sensor could be added to the running sensor setup section with maybe stride length options so the runner avatar would work? I’d be happy to Beta test any solutions. This could open the door to more Zwift customers who are injured runners/cyclist and walkers!
