Open or Create a New Page for each Shape

[NJBrearley]

Hi,

I have a network layout where a shape represents a more detailed diagram. What I'm looking to do is to be able to Double click the shape and either:

The diagram with the matching page name opens

OR

A diagram is created from a specific template where the name of the page represents a cell of shape data from the shape that has been double clicked.

From what I can tell the following DoCMD's could be used...
visCmdOptionsNewPage
GOTOPAGE("Prop.shapedata1")

However I cannot think how to assess if the page exists.
Any ideas?
