Current Bandwidth Utilization across multiple nodes

We are trying to put together a NOC View dashboard for management to post on a TV in our IT Area, and one item we would like to include is a Current Bandwidth Utilization for all our WAN routers, to show if any of them are peaking out.

Today, each router has the interface summary, which contains all interfaces and percentage utilization:

This uses the "Current Percent Utilization of Each Interface" report, but does not allow us to select only a single interface.

We've looked at creating a new view, but cannot find a way to generate the simple one-line view for only one interface, across multiple nodes.

Does anyone know of a good way to do this?

Thanks,
