Is there a way to automatically define the auto nav block when new single page or other type of page is created?

For instance, I've purchased and installed the Blog Package. Each time a new Blog post is created a new page is created along with it. This is the page that you will be taken to if you actually click on a blog post's title. It takes me to a page that has my theme applied to it, however, the navigation is missing. In order to add it I have to edit the page, add the autonav block and define the variables, such as what pages to include in the nav.

Thanks, alot. You guys rock.
