Almost perfect

Id like to be able to customize the categories. I dont like the pre-labeled ones. Id also like to be able to take the inventory list and make sub-categories for packing. I need an app that gives a full inventory list, plus has the capability to have it broken into where each item is packed.
For example:
Green:kids bag - list whats in the green bag.
Blue:husbands bag - list whats in the blue bag.
