6 years ago this is not possible at the moment.
what you are proposing impacts on the code to generate filenames (line 43 and 44), which is not difficult in itself: a more complex issue is how to represent the filename generation strategy in the configuration file and, more important, how to pass to the plugin the information needed to generate the filenames.
an alternative strategy to solve your problem could be that of generating index pages listing (and linking the books). That is, you could even try to use the plugin on the same YAML structure twice: the first time to generate one page per category (each page listing all the books in the category) and the second time to generate one page per book.

The example shows how to parse a data file and a property in the items. For example a list of books.
What if I want to have a list of book categories, with each category having a list of books, and generate pages for each book with the following folder structure?
category-id/book-id/index.html
