Bindings: Multiple Selections & Custom Classes

Short version:

Where can I find more documentation on how bindings works with multiple selections and custom objects? If I select multiple items in a list in a typical master-detail fashion, I can easily change values for strings and colors and such, but what if one of the properties of the selected objects is an array of other objects? I want to be able to add an object to each of the selected items.



Long Version:

As an example, say you have multiple Automobiles objects with a bunch of properties (name, color, year, whatever...) and each Automobile has an array of AutoPart objects which are parts of that Automobile. Naturally AutoPart has a bunch of properties itself such as name, part number, size, etc.

If you can imagine a master-detail view for this where there is a Automobiles list and detail view, and in the Automobile's detail view is a AutoPart list (for the AutoParts in the Automobile) and a AutoPart detail view, I want to be able to select multiple Automobiles and click an "Add AutoPart" button which would create two identical (but separate) AutoPart objects and add them to the autoparts arrays of the Automobile objects. Just to stress it again, I don't want the AutoPart object added to each array be the _same_ object, there should be two separate objects, but editable at the same time (like editing a color property of two selected objects in a color well).

Can anyone point me in the right direction of how to do this?
