Mexico AP xml Voucher Load

Hello All

I'm currently working on a client that is running PS 9.2 and integrating an acquired company into their system.  The acquired company has locations outside of the US in Mexico and receives standard XML invoices from their suppliers.  Is there a automated way to  load the XML invoices into PS.  The challenge here is that with the new statutory requirements that went into place recently they are required to capture a 36 character UUID.  Additionally if the invoices have to be entered online, is there a way/field to capture the UUID.
