I wanted to ask why the wall tool doesn't have the option to add insulation on each preset? I'm working on a simple 2x4 frame with drywall on both interior and exterior walls, however, there isn't the option to add insulation on the preset. Is there a way to add this manually? It's kind of annoying not being able to customize the layers of your walls accordingly. As you know, wall details always differ from project to project. Can you please help? Thank you!
