If you wish to add other template pages to your book front, click on the ellipse next to the Front Matter folder. A menu will drop down that has these front page options: Title Page, Copyright, Dedication, Epigraph, Table of Contents, Foreword, Preface, and Acknowledgement.” Put a checkmark next to the pages that you want to display and they will automatically populate.
If you want to add page templates to the back of your book you can do so by clicking on the ellipse next to the Back Matter folder. The ellipse will give you the option to put a checkmark next to the “Notes” and “Biographical Note” to a book. Put a checkmark next to the template page(s) you want to add to your book.
You can delete any of the pages that were previously selected for the front, or back of the book by simply unchecking the boxes next to the page.
But what if what you want to add isn't on those lists?
