Dynamic Discounts Feature

Hi,
I have setup the Dynamic Discounts and have a question.
I offer the discount on all products, is there a way that when the customer orders like 5 of the same item, they will get a discount. Is there a way that they also get the discount if they order 1 of 5 items.
So they can order 1 of product a, 1 of product b and so on.
I want to be able to offer my customers a discount if they order different items and not a set amount of the same product.
Hope this makes sense.
