Monthly Performance Report

Hi senior experts,
We have 5 boards linking to a central dashboard for senior team’s review. Since there are thousands of projects running in the parallel. Our senior team would like to have an illustration of monthly project status change.

I understand the individual board can have the “performance insights board”; however, can’t it be connected to multiple boards for an overview, and use SKU Vol on Y line? Ideally it can be similar to the 2nd diagram but with delta.
