How can I add/export audiobook chapters using Audition?

I am working on an audiobook and I need to export the audio track as a single file with all the chapters labeled correctly so that it can be used in the table of contents.

Is it possible to mark where each chapter starts and then have that chapter information embedded in the file so that each chapter name and timecode gets added to the audiobook's table of contents?

For example, the below image is a screenshot of an audiobook's table of contents from within Apple's iBooks app. I need a way to be able to mark where each chapter is within a single audio file so that I can have my audiobook's table of contents broken out by the preface, introduction, chapter 1, chapter 2, etc. 

Currently, I have to make a cut where each chapter starts and ends and then move it to a separate audio track. Then I export each audio track so that I have a separate .M4B file for each chapter. When that's done, I have to use a special tool to combine all the chapters back together again into one file. It's a pretty difficult process and I'm running into issues with how I'm doing it so I need to look for a better way to do this.

Any ideas?

(*chapter markers work in Premiere Pro for doing this exact task for Quicktime videos but I couldn't get that to work for my purposes with only audio. There's a youtube video that explains this better HERE.)
