Custom Game : Random Maps

Is there a way to create a custom game that selects random maps from a list? I created a Shotty Snipers game but I have to go in and change the map each match.

Side note: do you like a higher match win number or a lower win number with the best out of 5 rounds?

There is no way to automate map selection like it does in matchmaking.

And personally I’d prefer a higher win count.
