changing footnote styles in Pages

I wrote a rather long book using Pages. As I encountered things that I wanted to use as footnotes, e.g., from a website, I would just copy and paste into a footnote. When I finally got around to actually getting it ready for publication, I realized that almost none of them were in the right font, font size, etc. It appears that the only way to fix them is to individually select and changee them.

Is there any simpler way to retroactively fix these mistakes?
