How do we exclude imported AP Invoices from generating accounting

Summary:

Following a merger, there is now a requirement to import AP invoices from a third party system which are validated and do not generate accounting in the GL. These invoices have been accounted for and paid in the third party system, therefore we want to exclude these invoices from the Create Accounting process, and mark them as having Paid status. They need to be matched to PO's which we have migrated.

Is this possible to do?
