Add more data sources to title from template

I set up a Linux grafana server. Version 10.0.3

I installed Prometheus on a bunch of my servers and i found this template:

Node Exporter Dashboard EN 20201010-StarsL.cn

Honestly, the dashboard looks very functional and is exactly what I’m looking for. It’s clear that a lot of work went into this. However, the dashboard is poorly documented, and the GitHub page and blog are written in Chinese. I’m not familiar with PromQL so writing my own queries is (not yet) an option.

How do i add more servers to the following table?

My guess is editing the table, changing te datasource to ‘mixed’ and copy the queries while changing the data source, that doesn’t seem to work.

Can someone point me in the right direction?
