How do I either link two Address Book cards or have one card for two people

Question

I have a husband and wife I need to put in my Address Book, Joe and Jane Smith.
If I create a card for Joe Smith, then list both their email addresses, whenever I want to send an email to Jane, the address comes up showing HIS name: Joe Smith <[email protected]>
If I put both their names in the First Name field on the card (Joe & Jane), every email I send to EITHER of them is addressed as "Joe & Jane Smith <his/[email protected]>"
If I give them separate cards, as near as I can tell, Apple hasn't bothered to create a way to link them.
So how do I make it so that Joe and Jane are tied together in my Address Book AND both still see their own names when I'm composing an email?

Answer 1

That's a helpful idea, but not by much. I'm still stuck either entering every single bit of info on both cards (addresses, phone numbers, kids names and birthdays, notes — pain in the neck!), or trying to remember which one has that info for every couple.
Apple's "just do it our way" attitude is really getting old when they fail to build common-sense functions into their most basic apps.
