Sharing/Linking Populated Containers to other Visio Charts

[Recon1776]

Does anyone know of a way (trick, work around, out of the box, etc.) to share a populated container with another visio chart file?
Basically I want to use the same container that contains numerous items, shapes, text, connectors, etc. in another visio chart file and update the other files if the container and its contents change in the original file.

I tried to see if I could create a stencil file that contains the container as a shape that would then be imported into the other documents. It works partially in that I can bring that container over to another document, but I can't find a way to keep that stencil updated from the original file. It's also not much better than just opening the original document and copying and pasting.

Thanks!
