I've imported a MS Word doc into RH 2019 (new UI). The import created topics that are all "pages," as opposed to "books" (screenshot):
Now that I'm creating a Table of Contents for the project, I'm wanting to nest some topics under others. But apparently b/c they're all "pages" (not books), the "Move Item Right" button doesn't have any effect.
Is there a way to convert a page into a book? If not, how should I proceed?
