George, I truly appreciate your help on this and will look for your post later today.
Here's a link to a sample document: Dropbox - importTest_20150411_1.pdf
It contains a single button that uses some JavaScript, most of which is contained in a document-level JavaScript. You'll have to study it a bit to figure out how it works. It relies on using the cAttachmentPath annotation property, which really acts like a method to prompt the user to attach a file. If Acrobat is used and it's prior to 11, the normal type of file attachment is used, but this won't work with Reader unless the document has file attachment usage rights applied by LiveCycle Reader Extensions, which I don't think you have.
It is currently set up to add the attachment icons (when used with Acrobat/Reader 11 or greater) below and to the left of the bottom left corner of the page, so they usually won't be visible as they would be when a user manually adds a file attachment as a comment (annotation). Any comment attachments that are added will appear in the Attachments pane.
