Hi,
I am diagramming E2E process using BPMN palette. On it is very commun to reuse the same activity(node) into differents process. Each process is diagramed into different level of grouping. When I documented some activity(node) with differents properties is very useful do not replicate again the same activity(node) instead using the same node as a shortcut node referring to a previous one and update its data only on one point.
Regards,
