Command with option assign layer by Inputobject

The option to extrude multiply objects is already in Rhino 6. So that’s ok. But when I do this, all the extrusions will transfer on the current layer. I like to see there is an option that with the extrude command the extrusion stay on the layer of the objects. This option could be useful for more commands.
For example, command section has already this option to use the current layer or the input object.

What are the thoughts about this?
