I am writing a novel in which I sometimes add chapters in the middle. (e.g. b/c I split a long chapter into two.) When I do so, I then have to renumber all subsequent chapters. e.g. if the novel has 41 chapters, and I split Chapter 20 into 20 & 21, I have to manually change 21 to 22, 22 to 23...all the way out to changing 41 to 42.
The chapter headings are merely single lines in bold underline e.g.
is there a way to auto-number my chapters, so that if I add one in the middle, the others will renumber accordingly. (Just as if I have a numbered outline and add an item in the middle...?)
