Inserting Names from Contact List into Email Headers

Inserting Names from Contact List into Email Headers

When composing an email, when I click on the "To:" button to access my Contact list, I get a list with all of the email addresses, but only the First Names from my Contact list, I have to type the Last Names in manually.  Not a big deal, but I am accustomed to including the full names of my recipients in the headers of the emails that I send.  Is there a setting that I can change somewhere so that both the First and Last Names of my contacts can be automatically inserted into the email headers?  If not, maybe this is a feature that could be added in the future.  Thanks.
