How can I resolving more than one symbol at once?

I can do an Alt+Enter to create an interface for a missing Type symbol. How can I do it for multiple symbols for once. My use case : Say I copied a method form some place and I am interested in that method only, trying to understand what it does with out worrying about the classes and method implementations it uses/interacts with. And I want to refactor that method. How can I resolve all the Type symbols and methods on them by providing interfaces? I can do it one by one. How can I do it all at once. So that I can focus on refactoring only the method I'm interested in?

Thanks
