I've got leads who are given products in the CRM website, and I can add them to leads easily enough.

What I need to happen, however, is that different products have statuses unique to that lead. For instance, user1 and user2 have product1 added to their lead accounts. At this point, maybe user1 is up to "paid" for product1, but user2 shows "rejected".

Is it possible to have individualised fields on products? From what I'm doing now, changing any field in the product changes it for everyone, which is obviously a little bit useless.
