Hi there.
The EA online documentation shows how to map use cases to activity diagrams; let me quote:
"... it can be convenient to group activities into logical Use Cases. Enterprise Architect provides a convenient method of overlaying Use Cases onto activity diagrams while maintaining readability...".
The page is: http://www.sparxsystems.com.au/resources/map_uc.html
Further down on the same page I find:
"The Red bordered areas above are linked to existing Use Cases by setting the classifier. These 'Use Case Instances' then can be overlayed onto the associated Activities to indicate how particular business process is going to be implemented in the proposed system."
I believe this to be extremely useful in arriving at, and documenting, use cases and their design... but I have tried unsuccessfully to find more precise details on how to achieve this... i.e. given an activity diagram, given a use case, what are the steps to create such an use case overlay onto an activity diagram??
Cheers,
-olaf.

The red dotted line is a Boundary (click the New Boundary button on the UML Elements toolbar). Double-click to set the line to Dotted or Dashed, Ctrl+L to set its classifier, F4 to set the border colour.
HTH,
