Adding another layer on the heirarchy - Category Subcategories Channel

I am hoping to add a third layer to my Discord.  There are so many channels and we need them all, It would be great if there was one more layer.  I already tell people to minimize the Categories but it still isn't enough and we can't trim the channels any further.  This might be an issue for a lot of stock related Discords.
