It looks like the Help document does not provide all of the details. I checked my 8.1.3 system and see the 'Source page parameter name' field appears when selecting 'Create child case(s)' and Create multiple cases using a list.
To copy the data to your new case, you should be able to just include the desired page in your data transform as the source.
