To Be Done

This is the final PR to be merged into OML-Updates-Base before we begin the process of merging to main.

Note the end2end_up test data needs to be updated to allow the test to pass in this branch, but I'm electing to wait until this is merged into OML-Updates-Base so that we can do all needed test updates in the PR to merge into main.

Reviewed all of the /group/ changes, will review /segment/ changes in the morning. Just a couple small additions and two questions.

Makes sense. There will already me a "merge conflicts test updates" commit for the PR back to main so this will be easy to add.
