Say, inside menu 1 I have four commands, A, B, C and D. If I only want commands B and C to appear as batch buttons while also keeping them in the group of menu 1, I can only do so by creating another menu (menu 2) in which I include (copies of) commands B and C and set menu 2's attribute to "Treat as batch button". Therefore, I end up with commands B and C in two places.
