OS 10.4 - Mail and Address Book

Is there a way that I can make it so Mail will recognize a nickname from Address Book? Say, for example, I put my parents into Address Book, but when I write them an email I just want to write "dad" and have Mail recognize that and put in his email address...is there a way to do this? I know it isn't a huge deal but it would be nice if it could do more than just first,last names. And I know I could just fill it anything for the first and last names but I like it to be correct info for the fields.

thanks
