Must be able to allow a site maintainer to edit template in Contribute

I dearly hope contribute has the ability to edit templates, because otherwise I've got a nasty client on my hands. She wants to change sidebar items in the template and ripple those changes to all the pages similar to how Dreamweaver does, but she only has contribute.

If contribute cannot, there's got to be some other way to do this without having access to dreamweaver. Anyone know of a way?

Thanks for any help!
