Alternate bindings for a second keyboard

[WeeBull]

Not sure if this is a feature request or if I just can't work it out.

I have a laptop which I have my niri keybinding set-up for. This keyboard has discrete cursor keys / function keys / etc. I also have a compact ten-less USB keyboard which I frequently use that has shared cursor and function keys (i.e. I have to press a "fn" key to access the key-code). I can find that when I'm trying to use the keybindings for the laptop keyboard on the USB keyboard I can be having to press 4 or 5 keys to get something quite common (e.g. Move window to other monitor becomes Super+Ctrl+Shift+Fn+Left).

I'd like to have different bindings for different keyboards whilst both are attached and active. Is this possible?
