6 inch sub is not enough, but footlong is too much

I could get 6, but then I would need chips, cookie, and drink. Sometimes I am not in the mood for chips and want a footlong, but it's too much and have like 3 inches left. Subway should make a 9 inch. Either that or I have to get a 6 inch and a kid's sub. But then I will have to tell them the vegetables twice, or say "same for the other one". Doesn't really solve my problem though.
