Derive MyNode from DocumentNode instead of CustomNode. Then create a class MyNodeCollection that derives from CustomNode. Add a collection structure to MyNodeCollection (typically an UndoableList) that can hold instances of MyNode. Then simply add a single MyNodeCollection instance to the CustomNodeCollection.
