Friends Only option

Please add a Friends Only option for lobbies like in BL2/TPS.

Depending on level and playthrough, random players keep joining my game and every time I have to kick them manually.

When I want to play with strangers, I may choose the Open option to do so. But most of the time, when I want to play with friends, I don’t want to add them separately each time to be able to play with them.
