Right. 789-44 is THE CLASSIC BASIC CORRECT distribution block.
In the past I've had to come up with a smaller distribution block. I used two screw terminal blocks several 470 ohm resistors. In the 789-44, the IR buss ground goes to the minus of each LED and there's a 470 ohm resistor between each LED plus and the IR buss hot. Thus you'd need three resistors to feed a signal to three LEDs, for instance.
