Split file with target file suffix determined from tagged text within page

[Greg Merrick]

When I do a Word mail merge to create 100+ documents and print to a single PDF, I'd like a way to split them easily using a MERGEFIELD value as the suffix.  Currently I need to view each split file and then rename it using the value of a MERGEFIELD, which could be an invoice number or customer name.

It would useful to determine the suffix using text found within the page.  This text would be a duplicate MERGEFIELD with the font color changed to white so it doesn't print, but tagged in some way so it can be easily located by Nitro.
