I just followed a bunch of them from recent’ish PP rides (not TdZ) following Paul’s suggestion as well and had no issues. It looks like Zwift setup one per World but I got bored trying to confirm (for example, I followed 2 Coco’s, 2 Maria’s etc).
I wouldn’t bother selecting them from the Zwifters list in CA - each PP has about 30 versions of itself.
Not sure this was mentioned, but how about a “catch up” button or power up or something. You could start ride with your preferred RP, do you warmup, the hit “catch-up”. You would still end up with a straight line jump in the ride, but is would only be one activity.
