I'm trying to find a way to spatially group together folders in finder. I've attached a image of what I mean.

Does anyone have any idea how to do this without finder randomly resetting these back to a normal grid arrangement sometime later. I thought I had this working but after restarting my computer they all lost their positions.
I found that grouping folders spatially was really useful for keeping everything related topics together as not everything suits a perfect hierarchical structure.
Perhaps this is not possible; does anyone have other suggestions on how to achieve the same result?
Thanks for any help,
Patrick.
