I have some etudes books that seem to have pdf bookmarks already, since they appear in the dropdown at the bookmarks button. I'd like to know if I can take the TOC from the book and use it to link to where the bookmarks take you to, or in some other way have a clickable table of contents. I'd like to know this process in the case that I have other etude books that aren't coming in with pre-made bookmarks.
