Linking activity diagrams

[Jos Fries]

Hi,

In EA I can create an "activity overview diagram" which  shows the relation between several activity diagrams. I draw this diagram by dropping the activity diagrams as a diagram reference from the project browser onto the overview diagram and linking them with control flows.

In the overview diagram multiple control flows from different sources will lead to an activity diagram and multiple control flows will leave an activity diagram to different targets. These different control flows obviously have to be present in the nested activity diagram too.

Is there a way to express the linkage between the control flows in the overview diagram to the control flows in the nested diagram (and vice versa), something like the gate concept in interaction diagrams or the entry and exit points in state diagrams?

Any suggestion is welcomed,
