Rubber Cargo Compartment Mats

I, as well as most of you, no doubt got the Rubber compartment mat for the center console.
I saw on the '07's a small mat that sits in the Change Tray in front of the Shifter. Must be a New item for '07?

What I'd like to know is whether or not GM has a part listing for a Mat that is made to go inside the right and left side compartments in the H3 rear cargo area? I'd like to have something from the OEM, to keep things from sliding around in there. Not to mention, it will match the mats in the center console compartment and maybe the Tray.
