[Zope] Can I change the default document to index.html???

Has anyone figured out how to change the default document from index_html to index.html? To use products like Dreamweaver which only recognizes Zope objects with exstensions, the only recommendation I've found is to put the code in a DTML document called index.html and put "<dtml-var index.html>" in a DTML method called index_html.
