Clone TFS build definition in Visual Studio 2012/2013/2015?

Steps in In Visual Studio 2010

• Open Team Explorer
• Go to Builds
• Right-click on a build definition, and click Clone.

How can I copy/clone a build in Visual Studio 2012? The Clone operation seems to be gone?

Note: I am using TFS 2010

Cloning build definition is a feature that comes with TFS Power Tools.

I haven't tried it but it seems to be part of the beta version for 2012 available here: http://visualstudiogallery.msdn.microsoft.com/b1ef7eb2-e084-4cb8-9bc7-06c3bad9148f
