Hi Ryan,

For your use case, I believe there is a workaround:

• Assign the Visio file that displays the children shapes with the filter in the root view. You can filter by name using the option Name=RegEx
• Create another Visio file that displays a page from the previous Visio file assigned to the root view. In this new Visio file, you could use the shape data VdxPage (see Making a shape to display a particular page of the current Visio drawing).

Hope it helps.
