Search for All available PO's from the Invoice workbench

Hi,

is it possible to enter an invoice in the AP workbench and click 'MATCH' and not enter a specific PO but search for all available PO's for this supplier?  I thought this was possible but it seems to only bring back Blanket Purchase orders and not Standard PO's.

Does anyone know of a set up somewhere that would allow this from the invoice matching window?

Even if I put in a need by date range to search where I know there are PO's on it still brings back nothing for standard PO's unless enter the specific PO number

I know I can search in PO inquiry, but we would like to find from the invoice and match
