This is very easy. I've just found soon before.
You can create an additional interpreter from "+Create" button on "Interpreters" screen. If you want to create one more "livy" interpreter, choose "livy" from "Interpreter group". And then I can enable the additional livy interpreter by clicking the interpreter in "Interpreter binding" menu on a notebook that you want to use the interpreter on.
