UndoRedo grouping for multiple nodes being moved

I am performing some custom actions in the OnNodeModified handler.  When multiple nodes are selected and moved, this handler is fired once for each node for movement.  That's fine until I need to perform an undo.  How do I know within the handler that it will be firing multiple times so that I can group my actions into a single command?

You could defer your custom actions to SelectionModified handler when you detect Selection.Items.Count > 1.
