Overview widget in the board level

Is it possible to point the overview widget to use the groups as different projects to reference the “progress”?

If not, can you think of a way to visualize this?
I have X groups, with a variable number of items within, built out of the timeline, status, and numeric “progress value”,
And I want to provide the user with a visualized snapshot of where each group stands, rather than the entire board.

Any thoughts would be welcome :pray:
