I'm working with splitscreen, with 2 base cameras. Is it possible to add another camera(in fullscreen) that overlays both of them? (URP Camera stacking)

I am working on implementing splitscreen to my game. And I am working with URP camera stacking for certain effects when you open Options Menu. My players camera is the base camera. The UI Camera is an Overlay of that base camera. Right now in the multiplayer i want the same effect, but since there are 2 base cameras(for splitscreen) the overlay shows on both screens(as shown in the picture), but I want it to get the information from both base cameras and the overlay should show in fullscreen. Is there a way to make that possible?
