Is there any way of reducing the amount of wire in connecting LEDs to an LED64 phidget board? It seems that each LED has it's own ground. So my question is whether several LEDs could share the same ground by connecting one to ground on the phidget board, and then bridging the other leds to the led that has a ground connection. This is the way it would be done with switches, but wondering if it can be done with the LED 64
