A32 Pro Cross-Controller Control

[v1rtus]

I have two A32 Pro controllers—one installed on each floor. I would like to achieve the following functionality: when input 25 on controller 1 is activated, the output on controller 2 should toggle accordingly.
Is it possible to implement this directly using the controllers' software, or would I need to use an intermediate server or external device to achieve this?

Thanks in advance.
