Navigation at bottom of articles.

I'm trying to isolate blogs - for example, Site Blog, Review Blog, and Guide Blog. Each has a separate category and menu item.

One of the issues I am running into is isolating them. For example, at the bottom of an article in the site blog, it shows navigation to the previous and next posting, including not just the site blog but review and guide. I just want navigation to show articles in the assigned category.

Is that possible?

Thanks
