However, when an MR author is selecting a reviewer, there is no way to tell if the users listed as eligible reviewers were specifically listed or were included as part of a group. For example: `/dir_a/ @jane @john @repo/admins` Jane & John are individuals selected as CODEOWNERS, but if Jack & Sally are members of `repo/admins`, they will show in the list of reviewers as well, with no indication of the group being the reason they are an option. ### Proposal <!-- Use this section to explain the feature and how it will work. It can be helpful to add technical details, design proposals, and links to related epics or issues. --> Highlight group membership when selecting merge request reviewers that are populated from CODEOWNER groups, similar to how MR Approvals show what approval group the reviewers are in below their name.
