I have two questions regarding the use of curtain walls.

(1) Curtain Wall Panels.
I created a curtain wall system with a pre-defined grid layout. I want to change the color that several of the glass panels render, is there a way to change a group of panels without having to select them one by one and change their colour / material?

(2) Sloped Glazing.
I changed a roof to sloped glazing to create a standing seam metal roof. Once I do this, I loose my roof thickness (structure) capabilities. How would you go about getting a roof thickness showing again below the sloped glazing? Do I need to apply fascias and soffit? Is there a way to apply sloped glazing overtop of a basic roof, rather than changing the roof itself to sloped glazing?
