Cloning transformations
You can clone transformations. Select an existing transformation and from the list in the Transformation Designer pane. Click . Enter a name for the new transformation and click .
Note: The  button is not enabled until you specify a new
			name. If the name entered matches the name of the original transformation or is not
			unique, a red exclamation mark prompts you to enter a different name. 
 
	 New transformations created from existing ones using the function can then be amended to be variants of the original.
