How to manage Item account rules in a easy way without using expense account rules ?

Summary:

Manage expense account rules for items

Content (required):

We use expense account rules - Item to match an item to a special charge account, using the inventory Organization ...etc

For each item we have to do the same things, now we have only few items but in the future we will have more than one thousands items and it will be more complicated for maintainance.

Is there another way (more easier) to manage these account rules to an item (for example : BPA, or information defaulted from OU, BU and purchasing category) ?
