Does Oracle store unsupported file formats coming to Document IO?

Summary:

Suppliers sometimes send supporting documents like time-sheet and other excel documents which are not supported by Document IO which appear on the streams dashboard of the Payables Agent. Our client requirement is to capture such documents as attachment on the payable invoice. Does Oracle Payables Agent has capability to capture that as invoice attachment along with the original invoice PDF automatically. If not then does Oracle store these unsupported file formats somewhere in Oracle using which we can create a customization to put such supporting documents under invalid file formats as additional attachment on the payable invoices.
