Not really. First, it’s a one-to-many relationship, so there’s not a single note. Second, the annotation in the note isn’t directly linked to the PDF annotation — since the original annotation can be moved, edited, or deleted, the note simply links back to the original position of the PDF annotation. The connection there is a bit too weak to provide links in the other direction. As just one example, you could move a PDF annotation, such that the note was pointing to a different place in the PDF, but then would that dragged annotation still be listed as a link for the PDF annotation? Just doesn’t really work to go the other way.
