How to auto show "main-stream" instead of sub stream on live view?

[Sunnydays]

Within my live view, I need to automatically show the "main-stream" instead of the sub stream. How do i do this?

At the moment, every time i change the live view view, i need to select every camera and press "use main-stream" every time. Its very frustrating. I just want to show the main-stream all the time in live view.

I think it'll depend on the number of cameras you are trying to view.
The main/sub stream setting when you are viewing multiple cameras only affects what you see (not what is recorded).
Unless you are viewing on a large 4K screen, no point in viewing say quad view with more than 720p per channel (your typical 1920 x 1080p monitor isn't going to show higher).
