Layout fixed line scaling - Wish List

Maybe this option/ preference already exists but I am unaware of it. I would like to be able to fix my line scaling so that as I move around and zoom in and out, what I am seeing on screen with respect to line dash sizes is what will print on the sheet. In other words they stay fixed and are not constantly changing. I want to know what my printed sheet will look like before I get out of working mode and into print mode.
