Quicker monitor switching with UR824

I know you can switch where your outputs are going via the UR824 output routing page (when not in Cubase) but when I’m switching there seems to be no way to press one button to switch speakers.

Does anyone know of a quick way to do so?

Currently I’m making ‘Line out 1/2’ go to mix 2/3/4 (which outputs nothing, which is what I want), then changing line out 3/4 to mix 1 and vice versa when I want to go back to Line out 1/2. Is there a way to quickly do this with one click to A/B speakers without a monitor controller? It seems like it should be a simple task but I can’t find anything in the manual which will do so.
