Change default select settings in metrics page

Currently when a query is run in the metrics page, all results are selected.
When the users clicks on a result (on the color button of a specific result) this unselects that results.
I would like to propose to change this default, so that the click will filter based on that specific result and also allow multiple selections.

An example for why to do this would be :
I clicked, in the "Kubernetes / Compute Resources / Cluster" dashboard, on the "inspect" of the CPU usage panel and got this query
sum(node_namespace_pod_container:container_cpu_usage_seconds_total:sum_rate

) by (namespace)

I want to see the top namespaces that use the CPU and to filter by them so that I can see the trend.

I sorted by the value and now can't click only on the namspaces that I want to see.
Currently I will manually have to unclick all results and then click on the ones I want to see.
