Is there a way to display the full content of a Text Attachment on a Purchase Order/PO PDF report?

Summary:

Full Text Attachment content is not being displayed on PO or PO PDF print report.

Content (required):

The table and column which stores the PO text attachments (fnd_documents_tl, file_name) has a character length of 2084, but it only seems to store and display the first few characters of the text attachment. When we create the text attachment on the purchase order, we are entering the text content into the file name or URL field. However, once added and saved, the UI truncates the text with ellipses:

Similarly, when generating the PO PDF report for the Purchase Order, the File Name is again truncated the same way (note that I am using a custom PO PDF report tied to a custom data model. ):
