Simultaneous Multi-Layered texture painting/cloning/heal brush.

Just a tool that paints/clones (and hopefully somedays: healbrush) multiple layers with one stroke/brush. It would make cloning and painting easier with PBR textures (and also for other purposes) - normal map, bumpmap/heightmap, albedo, metallic etc. One stroke that would be copied to all layers (sure this means we need layer editing and hopefully it is coming in 5.3 or 5.4).
