Is there a way to Autocreate approved requisitions into a Blanket PO, rather than just a blanket rel

 We have just implemented iProcurement.  The purchasing manager would like to have ALL documents created from an approved requisition that comes in to autocreate through iProcurement.  This includes requests for Blanket POs and Contract POs.  From what I have read in the Purchasing documentation, you can only autocreate into Standard PO, Blanket Releases, Planned POs and RFQs.  It does not mention the original Blanket PO.  Is there a way to create a Blanket PO from an approved requisition?

Thanks,

Sue
