Set up a page for Page Not Found

In Bluehost, there was an option to set up a standard page when a page was not found within the domain, is how can I do that w/ jodohost? Is there an easy one or two step way instead of forwarding each individual page.

I ask because I set up zencart for a customer, but google shows her old pages so she’ll be losing sales.

Thanks.
