Could you add multiple contests?

I was planning to build one by myself, but searched your one, and seems it's already done quite a bit. I was just wondering, if there will be any option to use multiple contests. For now, one can play only 1 contest and that's why I cannot use it for education purpose. i want to take exams of a few students and they are in different groups. So I'll have to hold separate question papers

Thanks for opening a issue, I will start working on this.
