Dashboard - Cannot assign sub-item status column to Status overview

Hi everyone at Monday,

How do we assign the sub-item status column to the Status overview (Battery) widget for progress tracking?

My team manages several projects, each with a separate board. To further categorize the sheer number of tasks, we use sub-items exclusively. The ability we would like is to have the battery visualize the sum of all sub-item statuses.

Alternatively, can we achieve this through any other widget?
