How to Create a High-Level Dashboard Across Multiple Boards?

Hi everyone,
I’m trying to build a high-level dashboard that pulls data from multiple boards to track overall project progress and team workload. I want to see combined metrics like timelines, status, and key KPIs in one view.

What’s the best way to set this up in monday.com? Are there any widgets or setup tips I should know about?

Have you had a look at the Rollup Multiple Boards app?

from How many boards you wanna pull data from?
