So you can do a pattern like this:

chapter_title_add_pattern:Chapter ${index} - ${title}

Personally, I set strip_chapter_numbers:true and add_chapter_numbers:true and use the default chapter_title_strip_pattern and chapter_title_add_pattern (by not sending them in personal.ini).

So for the example above, I get:
1. Prologue
2. Chapter 1
3. Chapter 2 Named Chapter

...and I can see both what the author meant and absolute 'chapter' numbers.

Again, sorry for the misinformation.

Thanks for all the different examples. I think I'm more grateful that the chapter headings have worked so well with just the defaults.
