Adding tags for group rides

Some group rides ask you to add a tag after your name. How do you do that? I use an iPad for Zwift and an iPhone with the companion app. I have only done group rides like Tour of Watopia so far so maybe there’s an extra screen for changing name when signing up for these rides?

Nothing too special here, just change your name to whatever you want. You can do this on, in the game, or in the companion app under settings -> profile.

Ok, thanks!
