paste as link in activity diagram

[j33@1]

I have an activity, that encapsulates a bunch of actions, in one diagram that I would like to paste a link into another activity diagram. It seems to work but what happens is in the project view it moves that activity and children underneath the new diagram. Anyhow, I want to be able to reuse an activity hierarchy in more than one diagram and not change where it exists in the project view.

UML patterns seems to be the way to go with this. Only sort of draw back is I have to create the pattern in a separate diagram so I don't get to shortcut that.
