Question about the plate PCB

[sohocoke]

Hi, thanks for sharing a great design. I am looking to build a split keyboard with conventionally staggered rows and extra keys in the inside columns. I think su120 can save me the work of designing a custom PCB or a 3d-printable case.

My question is: is the plate PCB also designed to be separated per row / column and connected together with stagger matching the switch PCB? I'd like to have plate PCBs to stabilise switches in hot swap socket, and am wondering if I'd need to design those separately.
