I did a little test, and this is the result. I just made a copy and paste of my background from one layer to another. In your application, you can make 2 different cartridges with the values (retrieved from the 3D) you want, just switch from one layer to another.
Well, I just tested the layer solution and quite frankly, I'm amazed.
I knew the function under Autocad since it is used a lot but not under SW and I think that creating a background with 2 cartridges under 2 different layers is the best solution.
