Template variable of users in a team

Thank you for the fix per: https://github.com/grafana/grafana/pull/25698
Is there a milestone yet for implementation of deployed dashboards with Teams and “Team Members”?

Use Case:
Team represents one of our Customers
Users are the members of the Team
We want to use the new templated variables on the dashboard of a “Team Admin” that filters the query for data forma. specific User.

Thanks for your response,
Best wishes,
