I think, it's not hard to press F9 > Craft > X food, it will take your maximum 3 seconds.
I always wanted something just like this. whether it's fighting in wars, partolling, actively engaging in a CE, participating in a riot/anti-riot, it's hard to keep track of the food counter when it runs out and then you have 0 food while dodging enemy attacks or assaulting the enemy, it's definitely not a good situation to be in.
