uv mapping - facemap (each face whole uv space)

Im wanting to do face mapping on my object.
That is i want each face of my cube to be mapped from 0-1 range.

I can do this manually, but is there a way to do this quickly? The only unwrap tools I have been using are under the “u” shortcut menu. And I have not seen any others around…

doesn’t U > Reset work for you?
