Layouts vs Layers

How do people generally deal with needing the same Layer(s) on multiple Layouts?

I've got my first rough level-one screen/Layout done, with multiple layers, several of which are meant to be consistent across the entire game (HUDs, let's say), and are non-trivial. I now need to move the player to the level-two screen/Layout but I don't want to have to duplicate all of the work needed to make the HUDs. Do I programmatically build up (copy) the HUD layers from Layout #1, or is there another way to do this.

Thanks.

You could make a layout that contains everything you want across all the layouts (layers, HUD, etc..) and duplicate it every time you want to add a new layout.
