Relay device help

I’m looking for a relay type device which controls two circuits, but completely independently from a single switch - does anyone know of such a thing?

Use case: I have two lighting circuits which are on different RCDs but in actually in the same room (the landing) due to extension

I want to combine the two switches for these circuits into a single switch on the plate

It could be done ‘virtually’ by wiring say a Shelly 1 into each switch and setting a flow when one comes on to switch the other, or possibly with a Fibaro relay on each and setting association (i think??) but what I was really hoping for is something like a shelly one, with the switch input that when it switches joins two circuits, but independently

Does such a thing exist?
