I know you can sorta daisy-chain the Robot Inventor hubs with careful use of the light sensors (you can light up the LED in multiple colors, so you can use light sensors facing each other as a communication mode), though you'll have to program the encoding yourself. No idea if or how much the same kind of possible with the Powered UP hubs.
