Careers for Design + MBA

I’m planning to attend graduate school and I’ve been researching a dual degree - MBA and Masters in Design (you can get one at IIT, maybe some others).

From what I understand, this experience opens doors to some different career paths. For instance, I’ve heard of one person who is a portfolio planner. I need to figure out what those career opportunities are in order to know if I want to pursue them.

Can anyone on the boards tell me more about the types of careers available to people who have this dual degree?

Thanks for your help.
