Convert layer content to poly groups

Is it possible to have layers be converted to poly groups?
Would be very useful for example when I chamfer like in the image and would like to remesh for a clean mesh.


It is possible. Anything you do on a layer can be converted to a mask & masks can be converted to facegroups. Yay

Wait, did I miss something? How can it be converted to a mask??
Edit: Ohhhh that little mask button!!! Damn, I have missed this.
