Adding new layers not just copper

I have a questions about if it is possible and how to new none layers to a layout. A simple example, lets say I would different documentation on different layers. My case for now is creating a layer with dimensions in inches and one in mm.

Thanks,

Thanks,
That was my basic understanding.

So I will have to make different version of the board file to do what I want to do for the time being.
