From your post, I understood that you were looking for cutters to make simulated muntins, to give the appearance of multiple smaller panes while only making the actual door for one large pane of glass. It took me a while to remember where I'd seen them (although I'm sure that there are probably other vendors), but Eagle America has what I think that you're looking for.
Eagle Originals - Muntin / Mullion Cutters
As I read the description, you would cut the parts with the cutters used to make the main door (edge profile and cope cut), and then use cutter "A" to cut the notches where the muntins overlap in the center. Here are the instructions that are furnished with the bit.
