I know I’m late to the discussion but I found a pretty good workaround. Make sure you add your FTP on the Peloton in order to give you a power reading. First I upload the desired ride to my wahoo as an outdoor workout. On the Peloton I do a “just ride” or scenic ride”. I start the ride on my head unit and just match the wahoo’s prompts to the peloton’s power. It’s no Erg mode but way better than RPE. After the workout I delete the ride from the head unit. Peloton loads to Strava, which loads to TR account. Then just associate your ride with in your TR calendar.
