3ds Max :: Listing Bitmaps In 2011 Material / Map Browser?

I need to list all the bitmaps in my scene.

I've brought in an fbx that was created & materials applied in Revit. The bitmaps don't display on the model in my viewports, although they do render. I need to be able to make a list of all the bitmaps that are applied to this model, so I can go track them down and save copies into a folder.

Back when I was using Max 2009, I could open my material/map browser, set it to search the scene, and list only the bitmaps, not the root materials. How can I do this in 2011?
