Hide user on Accounts Preference Pane

Hey all, I'm using createUser.pkg to create our admin user for our images, and I used the "hidden" option to keep the user from appearing in the login window. However, you can still see the created user in the Accounts System Preferences Pane (including being able to delete that user if you're a local admin). Is there a way to hide the user from appearing in that Accounts Pane? Thanks, Jason
