Creating CMS Collection Interactions For Each Collection Item

I am trying to create an animation where the items in the left column of my CMS collection grid come into the viewing field from the left and the items in the right column of my CMS collection grid come in from the right. When I go to animate the items, all of them inherit the same animation. I’ve tried to create a combo class for the items using left and right, but this didn’t work since it applied the combo class to each item in the list. Is there a way to animate each item separately within a CMS collection?
