Hello... I am wondering if there's an easy (or not so easy) way to change a bookmark from one kind to the other kind. Specifically, when I combine PDFs, each source file ends up with one bookmark in the resultant PDF. These icons depict a "doubled bookmark"—two little bookmarks right next to each other, comprising a single icon. When I create new bookmarks in this PDF, however, the icon depicts just one little bookmark graphic.
Thank you to the community.
