does that help ?
I have to do some research here, i remember something awhile back and im not 100% but what i think happened is that the actual table limits the number as well as the code. But dont quote me on that, its just what strikes me at the moment. From what i remember it turned out to be that it was not possible. But as i said ill have to confirm that so give me some time to get back to you.
Thanks
