Adding text to bullet?

Hi everyone, I’m new to this program and am wondering how to set up a document so that it will automatically add a text label to a chosen level of the bullet hierarchy. There is an example of this in one of the included templates. (It’s called “Book Draft”). You’ll see in the second-level hierarchy bullets, the word “Chapter” is automatically added, and you can change the style so that a number gets included. (“Chapter 1”, “Chapter 2”, etc.)
Using this technique, I plan on making a template which will have bullet labels for PAGE, PANEL and so on, and I’ll be using it to draft out a graphic novel.
I hope I’m being clear enough. Can anyone here help with this? Much appreciated.

I managed to find some info online - it seems the ability to add an automatic text prefix or suffix to row bullets IS a feature - but not for the iOS version of OO. That’s unfortunate. I’m hoping this is something that is in the works for a future iOS release…
