Change all parameter of same subsystem in simulink???

Hello, I created a simple subsystem from a flip flop and several logical operator. Then Then I copy this subsystem to about 50 blocks and connect them together. Now I want to change some parameters and some configuration of the subsystem. For example seting up another initial value, adding a logical operator just before the input NOT How can I do it fast? I think about use variable to set up at initial time in callback fucntion IniFcn, but the second situation, when I want to adding a logical operator, I have no idea. Can you help me, please
