When I try to link (drag and drop) a chapter marker from the timeline into the menu area (orphan or flow chart), after I have selected a menu and buttons from the library, it simply reverts to the sequence 1. If I try to add another chapter marker it replaces the first.
Follow Bill's directions. I'll just say that I have no problem doing what you describe and getting multiple buttons and chapters. The only way I can approximate what you describe is to drag to the same button.
