Unable to add config transform

Question

I'm trying to add a Web.Dev.Config but I'm not able to. When right clicking on the original web config the option "Add config transform" is grayed out. The only config transforms that I have are Web.Debug.config, Web.Release.config and Web.Test.Config.

Why can't I add more?

First you need to add "Web.Dev.Config" in configuration manager.
