Create Folders or groups? iOS

I am currently studying and as I progress through the semesters, I was wondering whether there is a way to group all decks into specific groups for example Semester 1, Semester two Semester three deck etc.

If you swipe on a deck and rename it, calling it “semester1::child” will give it the name “child” under a parent deck called “semester1”. Some extra info: Anki Manual
