Currently, Bluebeam does not support exporting and importing or copying bookmarks from one file to another. Can this be added please?
Additionally, would it be possible to create an imaginary bookmark page? For instance, if you have several sheets of notes, can an imaginary note bookmark title be added with an imaginary page or just not reference any sheet? By completing this one can nest all note pages within that note subject of bookmarks. Without it, a new page would have to be created within a drawing set that is not originally part of that set. This can be used to assist in categorizing/organizing different types of bookmarks for faster access.
