Class setup to have 2 instructor dropdowns - 1st

Class setup to have 2 instructor dropdowns - 1st is required, 2nd is optional

I am currently having to create two classes for the two different instructors. Can you make it to be the same class has the option for me to list two instructors in the setup area. Instructor 1 needs to be required and Instructor 2 needs to be optional. If it applies to the class and I list two names, then both names owuld need to appear on the class schedule display page.
