show and hide connected shapes

[GVLewis]

Hi,

I'm a complete beginner to Visio. I'm trying to put something together that shows processes and documents that link to those processes. The connectors being between the process shapes and document shapes.

What I'd like to be able to do is have the ability to have the documents shapes hidden and then when a process is clicked it unhides the connected documents shapes.

Additionally documents may be linked to more than one process so it would have to work taking this into consideration.

Is this something Visio can do? Any help really appreciated.
