Group ticket headers in v16

I'm still testing V16 (1 year and 9 months later...). I realized that our VS department hasn't been using the group ticket headers we have set up in v15, but before I get them back in the habit I wanted to test it in v16. But there isn't a Group Entry Mode in v16's Access Control. Does anyone still use this functionality somehow? The documentation wasn't terribly helpful.

Thanks!
