You want the red point to be on the left and the blue on the right, and the two neutral ones in the middle in one column?
In your team_control_point_master, set your Cap Layout to 0, 1 2, 3 (assuming the red CP is 0, blue's is 3 and the two neutrals are 1 and 2).
Wait, you're right. My bad.
I managed to make something close with the layout 1, 0 3, 2. It looks more like this though. I don't think it's possible to do exactly what you're picturing, but here's hoping I get proven wrong on that.
Honestly it might be better for all the points to just be on one line (like 5cp push but with four points). It's less complicated that way and it'll be easier to understand for players.
