Adding a team manager as a member to a team

All members in a team should be able to see other team members and the managers leave on the calendar when the option for "who should have access to this team's calendar" is set to "team members and team managers", however the only way at the moment for team members to see this is to set the option to "all active employees". Can we have the option to add managers as team members to a team without having to set the calendar option to all employees?
