Automatically pop up of Supplier Catalog during Purchase Order Entry

Is there a way for the supplier catalog to automatically pop up during purchase order entry?

The scenario I have is:

One supplier (2000) with two different catalogs - e.g. PROJECT1 and PROJECT2

The item (123) I'm purchasing is in both catalogs with different prices

When I raise a purchase order using supplier 2000, I want the supplier catalog screen to automatically appear. The user then chooses the catalog they want and selects the items they want.

The relevant price then appears in the purchase order.

Regards,

Sam
