How do you 'calibrate & save' after using 'indoor rowing' on the Venu Garmin, the same way you can 'calibrate & save' after doing a run on a treadmill? I'm using SW version 17.04

Cannot  'calibrate & save' for 'indoor rowing' but you can for treadmill running directly on the Venu Garmin.  Please can this feature be added as distance is vastly out from the rowing machine distance.
