Additional Feature: Profile Picture/Banner Image Shuffle

While not crucial, as this could be done manually, I would love to see an option under profile settings to set multiple profile/banner images simultaneously, to be cycled through according to a set timeline. I imagine something similar to Windows 10 desktop background shuffle, which can be set to change your background daily, choosing randomly from images within a particular folder. This degree of personalization would satisfy my request, but I would be even happier to see an option to set particular images for particular days/weeks/months.
