New Post: Unique pricing matrix for every customer

I have a situation where every customer has a unique pricing matrix - and it is not rule-based. I need to load a separate set of "pricing files" per customer. Or maybe a better explanation would be a customer pricing "exception list". I have a limited number of customers, but each one gets special pricing on only a subset of line items. About 100 customers and 1,000 line items, but each customer might have a rule-based discount across-the-board PLUS about 100 line items having a unique discount only for that customer.

Is this possible to do?
Thank!
