How can I set a threshold for a custom group that only contains PDUs? When a group only contains PDUs the Current Power shows as No Data even though when you click on one of the PDUs it's PDU Dashboard show a wattage draw.

I need to do this as I run PDUs in Primary/Secondary with all servers plugged into both PDUs. The PDUs are plugged into different UPSs so if a leg goes out all devices rely on the other side. This means I need to monitor that my aggregate between the two PDUs is 5760W (80% of 7200w)
