[2019] We need the option to change lobby lead in custom games

It can always happen that the person who creats a custom game disconnects or crashes or has to leave. The lobby lead then goes to the person that joined the custom game first and it slows things down in scrims when that is someone who doesn't usually setup the maps or knows how to pause or someone on the enemy team.

I always have to check who to invite first when setting up a lobby, which is an annoying workaround for such a basic feature. The option to change group lead was there from the beginning.
