importing/exporting contacts as a delegate

[ornerytollbooth]

Hi,

I have delegate editor permissions on two people's Contacts folders. I want to add all of one person's contacts to the other person's folder. Can I do that without involving them and without using any plugins? I tried mounting their mailboxes, copying the first person's contacts into a subfolder of my contacts, and exporting it, but I couldn't select the second person's contacts as a valid target when I reimported.
