Recursive search when assigning materials

Hi,

We have put our .mtl files in Windchill in a folder structure where differents person have different responsibilities. The mtl files are named in the form Article_number_type_color.mtl.

When the engineer shall assign the material to a model, in most cases only the Article number is known, but not in which sub-folder. We have found that the Search function in the Assign Material dialogue only searches current level, is it possible to change the behaviour so it searches the complete structure?
