Customizable messages for when you're away or offline

So the idea is that when you message someone who is away/DND/offline, they'll receive a premade message (up to the user to decide) that be sent automatically to the sender. It's a modern-day voicemail, but for discord!


Ex: User1: Hey, you wanna play some games in an hour?
User2: Homework session time! Currently away but I'll check your message when I can! This message was premade for when User2 is away
