Using Supplier DFF/Supplier Site DFF to search for Supplier under Manage Supplier task

Summary:

The advanced feature under Manage Supplier does not provide site level or DFF level filter to search for Supplier. Is it possible to use DFF or Site information for Keyword search?

Or is there a way to include filters on Supplier Site and DFFs(on Supplier, Supplier Site) in Manage Supplier UI.
