Single device interface utilisation in NPM Home NOC view

Peeps,

I would like to a add a single device, single interface utilisation to my NPM NOC home view. What I want to achieve is a graphical presentation of our organistaion's interface usage, which can obvisoulsly be measure by the in/out on the interface of our Firewall.  I can see that graph when I drill into node itself, through NPM, en then go to the min/Max  average bits in/out.  I want that graph on my NPM home page, so I can show it up in the NOC view, which we present on a couple of large LCD on the wall.

thanks for your suggestions
