How to use Use Case Sub Diagram and Main Use Case Diagram

[moondaddy]

I have a Use Case which has an overall view of a process. However, it has
smaller processes that are a little complex and they need to be an a Use
Case diagram all of their own. I would like to drag these use case diagrams
of the small use cases onto the main use case diagram. And in a perfect
world, it would be nice to double click on the smaller use case sitting on
the main use case diagram and have diagram of that small use case open up
(for a drill down effect). Is any of this possible in Visio 2003 Ent.?

Thanks.
