The only way I've found is to "Go through the setup experience", found on the bottom right of the Machine Setup tab on all of your current computers that you want to link. This will give you a clean slate, so you'll have to generate a new security key on one computer and enter it on the other computers.

If anyone knows a better way, please advise.
