How to insert sub-swimlanes?

Is it possible to insert sub-swimlanes in activity diagrams? Does Visual Paradigm provide this feature? I suspect not, since I haven’t found how to do that.

I know that the business process diagrams allow that (Introduction to BPMN Part II - Swimlanes). For activity diagrams it would be almost the same.

I’m sorry that at the moment we do not support create nested swimlanes in Activity Diagram. We will consider to support this in our future release.
