How to track a 3rd app's map in Indoor Training mode?

I use Rouvy (a Zwift competitor) to control my Wahoo Fitness Kickr Snap trainer. I simply choose a Rouvy route and ride it. Is it possible to track the Rouvy map in the 830 in Indoor Training mode? I realize the GPS is disabled by default, as it should be, in this mode.

NOTE that I do NOT want the 830 to control my trainer, but rather Rouvy to control it because i want ride the course with the Rouvy video.
