Ring Pro 2 Corner Kit Angle

Hi, I've just upgraded from a Ring Pro to a Ring Pro 2. With my previous Ring Pro, I used stackable wedges to achieve a 45-degree angle, which was perfect. But with the corner kit in the box, it's only 25 degrees. and A lot of my view is angled too much at the wall side. I want to add an additional 20 degrees. The Corner kit supplied in the Ring store says it's not stackable and can only be stacked with wedges. But the wedges available are only for angling up or down? Is there anything I can get to achieve this? I am surprised that ring doesn't support this, as they did for the first gen pro.
