Linkback to PDFs?

[random1destiny]

Hey, I was wondering if there's a way to place a PDF into Omnigraffle and have it update when the PDF is edited through linkback or any other method. If not, this would be extremely useful as most other programs can export to PDF and I've love to be able to use those actual PDFs in my graffle diagrams.

OmniGraffle is able to LinkBack to PDFs created within itself, but it would depend on the other app supporting LinkBack for it to be able to do this with the PDFs imported from that app, not the other way around.
