We have the ability through actions to create a bill out of the documents module which then links the document to the journal entry.

When we create the bill from the PO and then upload the document to the document module we are unable to create that same associates to the bill.  If we upload the document as an attachment to the bill there is no way associate it to the bill in the document module.  Is there a way to easily create this association to a document in the library?
