Entourage New Message Address Book


Is there a way to format and set up the address book that shows up in the new message window when you start typing the email address. I have my contacts in categories, but that miniature version of the address book only displays the name and email address, hence i can't have my contacts clustered in the categories. Is there a way the categories column can be added, or the contacts sorted without having to put the category names as last names of the contacts (cuz this is the only way it can be sorted now).

many thanks
