We offer price quantity discounts and two of our products have quantity discounts on different attributes.

So they choose a type of lock (there are 3 different types) and get a quantity based discount and they can choose to purchase additional keys (different attribute/same product), also for a quantity discount. The problem is, when adding a certain quantity of the lock and then additional keys to the shopping cart, it will add the additional keys cost to the product price. So it charges too much. Hopefully this is making some kind of sense.

Just need to know how, if possible, I can set attribute quantity discounts without them interfering with each other.
