Min and Max Vertex Mass for Cloth

Hello! I have a little idea that I believe could significantly improve cloth dev in Blender. Blender cloth is more powerful than we realise. Vertex mass is one of the most important aspects of cloth. But it can't be controlled using weights. If we could have a min and max vertex mass and use weights & vertex groups to control it, we will have much more control over cloth behaviour. e.g normal shirt with a stiff collar (less weight provides much greater stiffness)

Thank you for your consideration!
