Joining the discussion a bit late, it could use a dot on pin 1 (which in the bussed or star version of this is the common pin). Again in the bus version (which is mostly what I use) the common sizes are 5, 9 and 10 pins for 4 resistors plus common, 8 resistors plus common and 9 resistors plus common. This was on my list to do once I get parts creation figured out but if someone else is doing it so much the better
