[Closed] Trainerroad: workouts in Zwift thru AppleTV

I understand the only way to use custom workouts on Zwift when using AppleTV is to create them in Trainerroad and be accessed as part of your training schedule.

If I understand this correctly, that means the specific workout you want to do has to be on your Trainerroad calendar for the day you want to do the Zwift workout.

I want to be able to access a couple of custom workouts whenever I want in Zwift so I was thinking of creating each one and adding to the calendar for every day so I could select any whenever I want.
Is this possible?

Secondly, will those workouts be available without an active TR account?
I'm not going to spend an extra $12 per month for TR just for this purpose but I would consider registering with TR for one month if the workouts persist...
