Add the ability for Indesign (and other PDF-creating CSS apps) to read the settings used to create an existing PDF.

I understand that this would require new PDF format feature: the ability to store the PDF creation settings in a PDF file directly. (I've added that suggestion as "Include PDF Export Settings in PDF Files" under the Acrobat feature request section.)

The goal is for a user to be able to easily export a new PDF with the same export settings as those of an existing PDF—something which is currently frustratingly difficult to do.
