Toggle to allow or rather whitelist messages from a specific bot or user

Bots are very useful in discord, and the fact that when you disable direct messages in the whole server that it doesn't let you get direct messages from ALL of them is very frustrating. If there was a toggle you could do on a bot OR users profile that would let you allow direct messaging for that profile specifically, without having to friend them (you can't friend a bot) this would solve the whole problem in a fairly simple manner.
