How to set Balance Ragged Lines as a paragraph style?

I was experimenting with Balance Ragged Lines after discovering that Adobe are trying to make it work on web text (seeing if it can handle dynamic text from data merge - turns out it can).

I couldn't find it in the Paragraph Styles options, and Adobe's help docs and everything else on it I could find just tell you to set it one paragraph at a time from the Paragraph window flyout menu, no mention of paragraph styles.

Is there a way I'm just not seeing?
