Menu links to break out of context

First, great module! We are loving the Context and Spaces modules and looking to use them to great effect. One question / problem I've encountered is trying to do links that should go outside the context. For example, we have a site that is similar in concept to 8Trees or Basecamp. When we're in a "project" context, we have a main navigation for the context tools like messages or tasks. We also have a utility navbar that has links back to the Dashboard (front), My Account, etc. The problem is that the links on the utility nav are autoprefixed by the Context module to include the current project. Is there a way to set some links or menus to NOT be prefixed?
