Edit position in CMS grid

Hopefully someone can help me with this CMS grid.
Here’s is a print from my design document. What I would like to achieve in my webflow project is to adjust how the collection is positioned. The first item to the left and the last item to the right, and then I would like to have two in the middle, see the design print.

The problem in webflow is that I don’t know hos to get two item in the middle in the columns.
Please help me with this!
