Not to open any worms but... you may be able to use your bonding screw depending on what type of panel you use. For example, GE has a true split neutral buss which allows you remove the MBJ with two bolts. Thus splitting the bus into a isolated neutral and ground bus. Then you could use the pretty green screw on the ground side (the left hand bus)
Do not confuse this with the short bus, which is what I rode to school in.
