Scrolling down to user defined workout on iOS app

I had an idea to warmup for time trials using my Tacx trainer, the Zwift app on my iPhone and the warmup I created on Zwift. Connected to trainer, and went to load the workout but could only scroll through the Zwift workouts. Am I missing something here, just curious. The workaround for me is to just do the warmup from the Long FTP test which is what I plagiarized anyway.
