How to add new subdecks to a collaborative deck

I created a collaborative deck with my fellow classmates. Are maintainers of a deck able to create a new subdeck and if so how are other maintainers able to see their subdeck? It is getting added to the overall deck count but we cannot view them under a seperate deck as tehy were intended to be used. Thanks in advance.

I am not entirely sure if making subdecks like this after you have uploaded the deck is possible. Can someone else weigh in on this matter?
