Meetups closed ride and late join

I believe if Zwift could add closed course and a 30 minute late join to meetups now there is a 100 rider limits and more world/course option, It would reduce the need for official group rides for the smaller groups/clubs,
When I do a banded meetup people who late join have to ride with so don’t get the band effect and spoils there ride, Also its very difficult to lead with 100 riders on a open course, please can you consider these options as I believe they would be beneficial to both Zwift Staff by lightening the need of official rides and the Zwift community making rides easier to setup and control.
