Dumb Multi-Display Mouse Question

[NortheastBreeze]

So I have a somewhat unusual monitor setup for my PC that allows my mouse to cross over only a small section of my 4k monitor. My question is, is there anyway to set it up for my mouse to be able to cross across the area I drew out with the blue marks without connecting them in the display settings? Ideally I want to keep monitor 3 centered above monitor 1 but still be able to send my mouse cursor from monitor 3 to monitor 2 and vice versa. Is there a way to do this so I don't need to use monitor 1 as the middleman?
