ExtendedPDF under OpenOffice 2.0

I installed ExtendedPDF in OpenOffice 2.0 under Linux and have a question that I hope someone can answer:

Is there anyway to set individual markers for PDF Bookmarks? For instance, I have a small instruction manual that is 18 pages long. Each page is one set of instructions. I want to be able to have a PDF document with one ‘folder’ called something like “Instructions” with 18 sub-chapters that show up in the PDF Bookmark tree. Is this possible? Any help would be appreciated.
