There are programs out there written by the IV guru's, but they do cost money. We investigated this a while back. I thought the price very fair, but it was not my decision.
I am not sure if they want to make it public or not. I think the topic discussion with the people who have the programs went off line.
Also, as mentioned, Vault will now do this properly. If you don't want to use Vault permanently, you may be able to set up a dummy Vault and just use it to do a copy design.
