How do I create a "blank-page-template" option to use in the Page Attributes-Templat pull

In Edit Page / Page Attributes, is it possible for the WPMU Dev team to add a "blank or none" option in the "Template" pull down menu? This page option would not display "reply", "comment" or "contact us" loops at the bottom. (I may not be the only person who requires this option.)

Thank you!
