Search for users: limit auto suggest results to project members

Hi. It seems like a simple issue yet I haven’t found any information on it:

When searching for Merge Requests and using e.g. the Author or Assignee filter, the resulting auto complete list shows a dozen of (public) Gitlab.com users.

Working mostly on private projects with our team where only members from that team will ever contribute to the projects, the auto complete list shows 99% irrelevant users and sometimes it’s very hard to actually find the correct user unless you know the exact username – which defeats the purpose of an auto complete list.

Hence the question: How and where can I limit the results of the auto suggest list to users in a specific group / project / etc.

If this is currently not possible, it should be a feature.

Thanks in advance
Alex
