And it is a good question, too.

Elements surfaces can be controlled through their internal dialog where all the parts are assigned separately, or more simply with an overarching material control.

If you look inside the Object/door/window dialog, you'll see a " Use Object Material" check box. This is the command that toggles from simple to detailed material assignments.

There is also a toggle in the info box.
