Calling Different PO Print Template based on Suppliers

Hi,

We have a requirement where-in we need to call different PO Print Templates based on Supplier Type. We have already Customized the PO Print Template to suite on such case. But now we need to call this Custom PO Print Template for only some perticular set of Suppliers. For others it has to print the POs in the Standard Layout.

I know the PO Print Layout selection is done based on the Document Type Setup, where-in we say for Standard Purchase Order Documents, pick this Template.

But this setup is at PO Type Level. Now we need to alter this selection to Supplier Level.
