Going to be "forking" this, manually, to try to get it across the line this week.

I don't think you can do this, though. PVs don't always run for the entire duration of a query window. Beyond that, for the "current" window, we'll have end times in the future.

Could you also expose VolumeHandle property from PersistentVolume somewhere?

Currently I see next data in /assets:

"Azure/82acd5bb-4206-47d4-9c12-a65db028483d/__undefined__/Storage/cluster-one/Disk/Kubernetes/pvc-c404ccf0-e136-41e3-901a-0ba6c43bdb40/pvc-c404ccf0-e136-41e3-901a-0ba6c43bdb40": {
      "type": "Disk",
      "properties": {
        "category": "Storage",
        "provider": "Azure",
        "account": "82acd5bb-4206-47d4-9c12-a65db028483d",
        "service": "Kubernetes",
        "cluster": "cluster-one",
        "name": "pvc-c404ccf0-e136-41e3-901a-0ba6c43bdb40",
        "providerID": "pvc-c404ccf0-e136-41e3-901a-0ba6c43bdb40"
      }

But I need to this resource id /subscriptions/82acd5bb-4206-47d4-9c12-a65db028483d/resourceGroups/mc_artur_artur-dev-cluster_australiaeast/providers/Microsoft.Compute/disks/pvc-c404ccf0-e136-41e3-901a-0ba6c43bdb40
