Varying discount on number of different products

I am looking to provide varying discounts for the number of different Woocommerce products purchased irrespective of the number of the individual products purchased. In this case I am looking at tickets for concerts, so if individual tickets are purchased for 4 separate concerts that would attract a discount but if 4 tickets are purchased for one that would not. Is this functionality available on this plugin? At first sight it doesn’t appear so.
