How do I add paragraph indentation to a style in iBooks Author?

I have a book with a lot of quoted verse in it, which needs to be indented. In order to make the verse distinctive to the eye, it's both slightly tighter set than the rest of the text, and left-indented.

I can set up the tighter settings and save them as a style, but there seems to be no way to indicate indentation in iBooks Author.

Currently I go in and use list indentation in each instance of the verse, which isn't the right way to go.

What am I missing?

Thanks!
