How do you include Front Matter in an Ebook Compile

I can’t find the setting…Also, for a dictionary, is there some way to identify the various letters as chapters? The Markdown setting would be
within Scrivener?

See also: §23.4.1, under subheading Front & Back Matter, in the user manual.


Iss there a way to accomplish this without spltting the text into 26 chapters?
