3D Coat layers folder doesn't support Pass Through as far as I know and this make it (folders) a bit useless if you want to organize layers with independent blending modes inside. Nowadays any paint software has pass through, enable by default or as an option to be activated if you need it. Krita, Photoshop, Affinity, GIMP....  You will find pass through everywhere because it's part of a common workflow and allows better organization of layer stacks that serve the same purpose.
