Jim,

Yes you can add a property "As" a collection. I don't have any quick examples or articles to point you to but I have seen it in code (I just can't remember where). You first create a class that inherits from a collection class. Then you base your property on the custom class. The Get and Set of the property would access methods of your custom class to extract the data you want. Hopefully this helps.
