Is it possible to add an ad hoc email address for a PO communication? 

Example, requisition is created using an order site, which has a default PO communication method. The shopper creating the requisition needs the PO to be communicated to a different email address, different than what is on the supplier site. On the Enter Requisition Line or Request NonCatalog Item, after you select the supplier + site, there is a field labeled Email, when entering an email address in this field, the PO is not sent there but to the communication method associated with the site.
