Can Contribute edit a DW template and allow it to propagate?

I've created a fairly straightforward html/css site in DW CS3 based around a template and have uploaded both the site and template to the client's web server.

There's a little set of static text on the template which cross-populates all the html pages. If I edit the template in DW, it updates all the pages that are based on that template. I'm hoping that if I set up the client with Contribute, they can access the template, edit it, and see the changes propagate to all the html pages that are based on that particular template.

Is this possible? If not, is there a breathtakingly simple approach I might be able to give the client to use?

Many thanks.
