OS X V10.6 Snow Leopard :: Nickname Field Listed Into Field Of Apple Mail?

If you have a contact in Addressbook (AB) with a nickname, if you also use Apple Mail (AM) and create a new email and start to type the contact's email in the TO field, AM will finish your typing giving you a list of related possible email addresses to choose from. The problem is that in addition to the email addressk AM adds the contact's nickname as opposed to it's firstname/lastname or even business name. We need a preference for this, per contact. 

Example: In AB you have a contact: 

Name: Jon Doe
Company Doe Company
Nickname: The Doester
email: jon.doe@doecompany.com 

In AM you start to write an email: and type: "jon" and AM shows you a list of possible related emails one of which will be: "The Doester" [URL]Commentary: now if a casual email to a friend, this is OK. But what if this is a business oriented email and "The Doester" isn't appropriate? You can only stop the inclusion of "The Doester" by deleting it from the Nickname field in the AB. This is presumptuous on Apple's part, or a bug, that the Nickname should trump the first/lastname or company name. 

I don't exactly know the answser to this. If we could easily choose which name to append in front of the email address (firstname/lastname, company name or nickname) that would be cool. Or maybe no name gets added if it has to be: all or nothing from a programming point of view. But having nickname as the primary, if it exists, can be a problem in certain correspondence IMHO.
