Currently for most of the previous mentioned things you can select (maps, gamemodes, heroes) you can only have them be random by least frequest the normal vote or ordered. i think there should be a draft setting for this (maybe with some advanced settings). so for example if you have like 10 gamemodes total you can have 5 (or all) be selected and then the players/teams go on by banning 1-3 at a time till they have come to a final gamemode/map. so here an example with 8 maps Player/Team 1 bans 1, Player/Team 2 bans 3, Player/Team 1 bans 3 more and then Player/Team 2 bans 1 (or just selects the last one).
