Import WDS 3.01 into WSUS 3

Hello,

We have WSUS 3 and i have read in the Internet that some people have the 
Windows Desktop Search 3.01 for XP in the WSUS Updates.
But i dont have this Program. So I wanted to add the Update manually to 
WSUS, but I only can find WDS 2.6.5 and 2.6.6 in the Update Catalog.
How can i make my WSUS ready to deploy the WDS 3.01?

Thanks
