vROp's 6.0.1 Dashboard configuration

I'm trying to create a dashboard which contains the Object List widget (pointing to Adapter Types > Container) and Scoreboard widget. The Metric Config XML looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

  <AdapterKinds>

     <AdapterKind adapterKindKey="VMWARE">

         <ResourceKind resourceKindKey="VirtualMachine">

                  <Metric attrkey="mem|granted_average" label="Memory Granted" unit="KB" yellow="50" orange="60" red="80" />

                  <Metric attrkey="cpu|corecount_provisioned" label="CPU Core Count" unit="" yellow="50" orange="60" red="80" />

                  <Metric attrkey="diskspace|provisioned" label="Disk Space Provisioned" unit="GB" yellow="50" orange="60" red="80" />

        </ResourceKind>

     </AdapterKind>

  </AdapterKinds>

Unfortunately the Scoreboard never populates with anything when the Container object is selected under the Object list. It only works correctly at the VM level. I'm trying to pull these metrics into the Scoreboard using a group of VM's (VM's associated with a Custom Group). Is there another way to select the Container Group and have it populate the Scoreboard with Memory Granted, CPU Core Count and Disk Space Provisioned for all the VM's in the Custom Group?

I might add I have a Supermetric setup using the individual custom groups and this works great except there are so many groups the home page tabs are cluttered now. I thought the Object List widget would be a better option.
