Hello! I'm hoping that someone can help me out here. I frequently use the same materials and I was wondering if there is any way to change the default textures/ colors so that every new project starts off the same. For example: on exterior walls CA defaults to blue lap siding; bathrooms and kitchen default to a cream tile; walls, windows, and doors default to Brite paint; etc. I'd like to change these so that I can save myself time. Can someone explain how to do that, please? Thank you!
