Modify H1 Headline for SEO

I don't use the Blog Title option for my layout, which is typically given the H1 Tag. All my posts, and page titles are using H2, which isn't giving me the benefit of H1 for Google SEO.

Is there a way to have Atahualpa assign H1 Tags to post headlines and H2 tags to "linked" post headlines, like would show up in Excerpts? This would give me the H1 tag on individual post pages, but keep multiple H1's off on a category listing page of posts which Google doesn't like.

The "Post/Page Stying" menu has options for CSS styling of each of these items, so I'm guessing some ID is being generated in Atahualpa for the different headline states.

Thanks in advance for any help!
