I did, in fact, put all the chapters in one file instead of individual chapters per file. The latest chapter will be in the back (natch), but in the PDF, your reader will open up to the correct chapter automagically. The Kindle and EPUB have links on the title page that will take you to the latest chapter.

I did this beginning with chapter 23, but I failed to let you know. For new readers, if you download chapter 24, you’ll get the whole thing up to this point, so you will have no reason to go back and fetch each chapter individually. And welcome to my world!
