Multiple Recommendation offers on the same page showing same content

Hello, I'm building an A/B test that will have multiple Recommendation offers on the page. Is it possible to build in logic, if not already taken into account, that will prevent the same content from showing up in Offer 1 as in Offer 2?

Example being, we're working to deliver recommended articles in multiple locations on a page but sometimes the same articles get recommended in each location. How do we avoid this?
