Niagara Instance Module Like Cascade

Hi everyone. i have been working in Niagara from some time and one thing that really frustrate me is i have to do same module setting in each emitter. so is there any way to make modules instance like in “cascade”. Like i want to change color of my all emitters at once like i can in “Cascade” and one more thing guys can we export Niagara emitters from Niagara system.

maybe user.variables are the answer?

can you show me how?! it will be really helpful.
