How to provide cascading panels

I’m new to Grafana, but we need to build cascading panels. What we have are several similar systems and we want to provide a detail panel for each system. From some metrics, we calculate a system state and we want to build an overview panel providing only the calculated state of each system. Because the state vary over time and depends of the time interval, It’s not possible to held the state in the datasource.
Is it possible to get a summary state out of a panel and display that value in another one?

Thank you
