I'm sure this has been asked, but I cannot find it. I want to have a notebook-looking windowskin for one menu, and a pure black windowskin for another sub-menu. blackmenuskin.png and notebookwindowskin.png.

Do I need to make separate Window_Base to do this, or can I add some snippet of code to Scene_NotebookMenu or Scene_BlackMenu to change the windowskin on the fly as each menu is accessed?
