Repeating old custom workouts

Hi, have been using Zwift for a few years now and recently I was working with a coach who would upload bike workouts for me that I completed on Zwift, it was all automatic so I only needed to select the workout and crack on with it!

I am getting back into training and wanted to repeat some of these workouts so can anyone let me know how I can select an old custom workout and simply reupload it so that it syncs again with Zwift and TP? I’ve got a Zwift subscription, TP premium and can see all my old workouts on Zwift companion, I just can’t figure out how to run them again.

Thanks!
