title: WebApplication publish to relative filesystem path
body: <p>I'm setting up a publish to a relative path for testing locally (especially xml config transformations). Each developer has their own path to the checked out project and I'd like to set up a publish that is machine/environment agnostic.</p>
  
  <p>The publish dialog doesn't hint at any variables or wildcards that are allowed in it and it doesn't accept <code>obj\publish</code> or <code>file://./obj/publish</code></p>
  
  <p>Is there a way to publish to a relative filesystem path?</p>
