In Snow Leopard there was a way to select which address to use for each contact in a group, for sending group emails or printing address lists. This was done by selecting the group in the groups column and choosing Edit → Edit Distribution List…
In the (horrible) Lion Address Book, the feature is still in the Edit menu, but I can't figure out why it's always dimmed. What are the circumstances when this menu item should become available, or how can I choose the addresses for my contact groups in Lion?
