Two different chroma key backgrounds

I have the Studio Pro HD. This comes with 1 USK and 2 DSK. We are doing 2-camera live interviews in front of green screen. Here is what I'm trying to accomplish but I don't know if it's possible with this switcher so I'm wondering if I need to upgrade:

I want to be able to switch camera angles and give the appearance of being on-set so that the background looks different and at the proper angle based on the camera I'm on. I have taken a high-resolution background and created the two different angle backgrounds so that they match and make sense based on the camera angle, but I cannot figure out how to switch between the two angles and have the background change also.

Does anyone have a way to do this?

Thanks.

Set up 2 Macro's. 1 for each angle where you change the media player and camera input at the same time

Then switch with macro's instead of PGM PRV buttons.

Thanks so much. This really helped and is doing exactly what I wanted.
