Help - display same camera view while rotating thru multiple views

[Bigazonk 0]

Hey all, newbie here. I recently installed a 8 channel DVR system with 8 cctv cameras and 2 IP cameras. My issue is the DVR I purchased (Annke) doesn't support the views I need.

Here's what I'm looking for. I want the cameras to cycle through 2x2 but I was the top left camera to always display CH1 (front door). Is there additional equipment I can add to achieve what I'm trying to accomplish or can someone recommend a DVR system that will allow me to configure like this? I've searched high and low, but each company seems to use different lingo. Thanks!
