Auxiliary Lighting W/ Encoders

[The_Waffleing]

Okay so allow me to re-phrase this in such a way where everyone here can hopefully understand. The situation is that our auxiliary board is using 15 LEDs as indicators. Mind you, these are physical LEDs that are being used on a controller board that is not connected to the robot but is connected through the computer and is used as a third joystick device through the driver station. The situation is that if one were to use the first option in the game-pad configuration tool there would only be 11 terminals for indicator lights. The question to those on Chief Delphi is this, Can we use an encoder on the controller to accommodate for the quantity of lights and if so how would one go about achieving that? Are there any other ways to accommodate the number of lights using the LaunchPad that I am unaware of?
