Must multiple versions of P43E060 be used to generate different PO doc types from Requisition Self S

Hello Community,

In Requisition Self Service when we generate/expedite purchase orders, we need to create one of four different purchase order document types. Do we need four different versions of P43E060 on the E1 page menu? Can we indicate the PO doc type somehow before getting to the expedite process?

Thanks for your help.
