Saving selected pre-made workouts to my library

I use an iPad/iOS for Zwift, and I like to use the pre-made workouts for my structured training, but it’s incredibly frustrating that there is no search capability in the app.

I identify a workout at the What’s on Zwift website, but there’s no search capability on the iPad app, and I usually can’t find it again by browsing. I’ve also saved some of the pre-made workouts that I’d like to do later, but can’t access them in my library (I do have my own custom and Training Peaks workouts).

What am I missing? Why is there no saved library function for pre-made workouts?
