2 Arduinos and Display 1 USB

Hello, I currently want to make a custom racing wheel and I want a display in it. I haven't worked with SimHub before, but I currently have 1 Arduino Leonardo for the Buttons and encoders and I wanted to add a Display, but I only want 1 USB Cable come out of it. What I thought about is sending the Data trough Serial from the Leonardo to an other Arduino with a display attached, but I can't find how I can add such a method in SimHub. Is there any other way how to achieve that or where is this kind of method in SimHub?
