Collection Item custom styling

Hey, so i have a design i wanna accomplish with a cms collection.

So, thought i could do just one item and in this item two values are stored, but that doesnt go well with the sorting. So i cant use flex direction reverse, since its all in one wrapper and each child has 50% width. I cant use css nth child either since it is child 2,3,5,6 etc are different.

So, what is the best approach for this?
