Pre-Selecting a Contact Page Deparment?

I'm working a page that requires us to link to the contact page. The contact page uses to the built-in contact module. To help usability and interaction I'd like the particular department that the user needs to be contacting selected by default when the user clicks the link. It should only do it from this page.

Perhaps a special link like: foo.bar/contact=?baz (where 'baz' is the department we want)

Is this possible? Thanks!
