Rotating/Moving in Z direction

Hello all, I'm brand new to grasshopper so sorry for asking a beginner question.

In the image below I have this "Roof Structure" and I want to be able to manipulate each individual panel but only by rotating it CW or CCW perpendicular to the x-axis , and moving it in the X direction.

Also I can't find out how to tell grasshopper that I want to manipulate the object, is their a command to select my pre-existing rhino object?

Thank you!
