How to have SEO URLs incorporate more than just the name of the product?

When you generate SEO URLs according to the IBM tutorials, you end up with URLs that look like this for a book called "Death wears a green hat":

http://www.shop.com/mystore/shop/thrillers/death-wears-a-green-hat

How do I configure it to generate URLs that incorporate more than just the title, eg. the author name:

http://www.shop.com/mystore/shop/thrillers/john-doe-death-wears-a-green-hat

I can hack the seourlkeywordgen batch file, but what about delta updates to new products?
