No, I'm finishing it, using the Finish & Merge function.

The original document, once fed a data source, offers the full mailing functions and multiple records. I hit Finish & Merge, Merge to New Document (Current Record), and get a fresh document containing a single record and not linked to any data sources. This has no field codes so Alt-F9 does nothing.

Once saved, File > Edit Links to Files shows that the new document is linked to the image on my M drive. It retains this link when emailed.
