Question: Is there are 'best practice' guide for creating replicates of activity diagrams in Cameo Systems Modeler?

Context: 

• Bold fonting the words below is an attempt to deliberately make the distinctions explicit. That said, I'm still learning the terminology and this is contributing to the issue below.
• An existing activity  is documented in an  activity diagram containing swimlanes + call behavior actions. 
• I want to replicate this existing activity including the swimlane partitions into a new activity diagram within the same project and make minor edits in order to document a similar scenario (activity).
• Per section 6.8.2 of Delligatti SysML Distilled: Each call behavior action has a defined :
  • For example: : 
• When I copy the activity and attempt to rename the call behavior action, this does not result in a new call behavior action which is my intent. Instead, the original call behavior action gets renamed.
• I recall learning how to do this correctly but cannot find the reference in the following books I have on hand.
