Multiple chapters

Sorry if can´t crearly show what I want, but here is another attempt to explain it. If I create an scorm title in Lectora I have to create one AU (Assignable unit) for each elemnt I want to display on the learning path. I know I can create chapters and sections within an AU, but I can´t figure the way to make those chapters appear on an scorm Learning Path. is it more clear this time? Thanks
