There’s a PDF bookmark script floating around here somewhere - downloaded mine last year sometime.
When you’re on a specific page of a pdf, fire up the script - creates a bookmark link in a smart folder, back to that specific page. Will see if I can find it.
EDIT: Reading through what you asked for again, don’t see the above being much help. Will result in a multitude of “bookmarks” spread-out over the smart folder, probably not what you’re wanting either.
This might be more useful: [url]QuoteHighlight&Annotate script]
Each time you run the script, after the initial RTF is created - it simply adds the next quote, and the page it refers to, to the same RTF. So you could have a RTF doc with multiple links back to specific pages within a pdf. It should also be possible to set up a keyboard shortcut to execute the script, so that would save time.
