How do I set my course category?

hello everyone!  
I am Yue, and I am currently taking my first course.
My course is focused on regional economic investment analysis, which belongs to investment opportunities. I have found that the categories we must choose when developing courses are very limited for investment analysis of an economy. There is not even a category called 'investment opportunity'.  
I hope Udemy can expand this category.
