Copy and Paste States and their properties

In the editor, it would be great to be able to Copy and Paste Properties of State from one item to another.

For example, copy the States and / or Properties from one button, and paste it to another button.

It would pop up a list properties that you could choose to copy so you can be selective. 

Once you've selected a number of properties, these would be selected by default the next time you copy state properties, so that you don't have to select them every time.
