How to let users review multiple categories?

I saw in a tutorial (https://www.youtube.com/watch?v=qCoT1sr7rPg) that users can review multiple categories, however it’s an old tutorial and I can’t find where to do that in the current version. I only see the add categories but when I go to leave a review it only let’s me select a category for the review, not rate multiple categories out of five. How do I make multiple review categories like that? Thanks!
