Ability to Link Groups or Label Group

I want to have the option to link or label Groups in boards and workspaces so that in a dashboard, I can view all tasks, files, etc. related to that specific Group title.
Ex: If I have three boards with different information, but they all have a Group with the same title, “client 29”, I want to be able to set up a dashboard view of Client 29 to see everything going on with that client across all workspaces and boards as well as all files associated with that group name.
