Backup camera & surround camera separate?

[MilehighRam]

When i go into reverse, I can either have the backup screen (which takes up half of the 12" screen) or a smaller version of the backup and surround (taking up the upper portion of the screen). is there a way to have the backup camera on the top half and the surround cameras on the bottom? Im thinking there isnt, but that would be awesome!

Would be excellent but haven’t seen a way to accomplish this.
