You need to copy the file out that the WixUIExtension is using as source.
If you download the sources, you can grab it right out.
Your error is because you're naming a dialog the same as an existing one.
Give it a unique name, then change the "Next" and "Previous" actions to
match what you're expecting.
Adding and changing the dialog flow is identical. If you know how to add a
dialog into the flow, you know how to change it. It's the same mechanism.
