Gmail notes folder to be shown in My Notes

Only my MSN notes appear in the My Notes app in Outlook, all notes from the other mail accounts, like my Gmail notes, don't. The reason is obviously that only the MSN notes folder is really a folder containing elements of the type "Note", presented with IPM.StickyNote. All notes folders from the

other accounts are mail folders containing elements of the type "IMAP", presented with IPM.Post,

What can be done to overcome this and also make the other notes folders appear in the My Notes app in Outlook?
