Make a playlist for Audiobooks in the Books App?

Is there a way to make a playlist for audiobooks in the books app?

You can add podcasts to a play next kind of list in the podcast app but not audiobooks which is baffling to me? I need to have something playing as i sleep but i cant do that with any of the audiobooks i've purchased because it doesn't have this function seemingly.
