Rotate North

I’d like to do a Sun Study on a project. I’ve set up the project using X+Y has horizontal and vertical, but the project will actually be oriented 72deg west of North.

I’d like to do an accurate sun study without having to rotate the objects in my project. Am I able to rotate the North point for the Sun?

Thanks,
A

There is a north control on the sun panel.

right under my nose- ha! thanks Andy!
