New notif sounds are great!

I know these seasonal notifications are only for December, but will there be any way, like a command or a little button in the Accessibility Folder thing to keep the notifications on after they're gone, or select which ones to keep and which ones to revert back to normal? As a lot of them are really nice, and others not so much, and I'd love to keep the good ones, and revert the bad ones, thank you and I will be watching twitter for new updates!
