How do you merge duplicate contacts?

I recently adding imported a list of contacts.  I had a lot of duplicates (that were already in my contact list, some with different information), assuming that Outlook would be smart enough to merge them.  Instead, Outlook just linked them.  Now I have dozens of contacts with duplicate information.  It's a complete mess!

Is there no way to completely merge duplicate contacts?  The linking system is great for separate services... but completely pointless when they're all Outlook contacts!

Please tell me there is some way to merge!

Thanks
