Team Dashboard

I want to be able to have a "Team" dashboard that any person can use and it shows them the tickets that are for the team that person is part of. It is similar to how the function currentUser() works in filters to apply to gadgets in the dashboard.
So instead of doing a filter that looks like this & each team manager having to create a copy & a copy of the dashboard:
project = TT AND Categories not in (Project) AND (assignee in membersOf(OPERATIONS_SRE) OR "Assignee group" = OPERATIONS_SRE AND assignee is EMPTY) ORDER BY priority DESC, duedate ASC
I want to be able to do this for one dashboard that every manager can use for "their team":
project = TT AND Categories not in (Project) AND (assignee in membersOf(currentUsersTeam()) OR "Assignee group" = currentUsersTeam() AND assignee is EMPTY) ORDER BY priority DESC, duedate ASC

Ps.: This functionality probable require a definition of a new entity on the user model: "user team". The list of "user teams" differ from the list of user groups because the last one include all the login groups.
