When you create a bookmark and add nested icons under it, there's no way to move it back without deleting it. Can you all the nested icons to move without having to delete them? For example if I have bookmarks A,B,C, D then I add 1a, 1b,1c and want to move 1b to align with A, instead of being indented, I cannot do it.
See the attached document of trying to align bookmarks in a .pdf booklet.
