Grafana Assign Selected Result to Variable

Question

I have a Grafana panel which displays a number of results as shown below:

If I select one of the results, say 11.EsAction.95.percentile, I would like the value EsAction assigned to a variable $Action. Once I have this, I can update results in a different panel.

Or, if you a more clever way of updating a different panel based on the selected action, that would be much appreciated.

Thanks in advance.
