[Suggestion] Add a feature to temporarily invite people to a server.

It would be nice to have a special server invite in which the user I send it to can enter the server for a specific time. It is great if you have your server with your friends and there is a new person who you and your group want to play with. Now, you can add the new user to your server but then it remains there. It would be nice as a feature to be able to let a user into the server for a certain time.
