Is it possible to determine if New or Existed folder was selected in the WiX?

Question

There are PathEdit and DirectoryList controls which are associated with the same string valued property. That property is the path selected by the user. When user press NewFolder the DirectoryListNew ControlEvent raises. This event notifies the DirectoryList control that a new folder must be created; it creates the new folder, and selects the name field of the folder for editing.

So, is it possible to determine if user select existed folder in the DirectoryList control or select to create new one?

Thanks.
