There is not. It was assumed streamers would change streaming software scenes after a match. It is also nice to still have access to the players after a match so you can lookup their stats and discuss the match.
But is sounds like it could be an option. I will have to search some log files to se if a match ended section occurs.
Will use it on stream the next days. I play 1v1 mostly but switch to 2v2s also. My issue was that 2v2 would always be showing. Anyhow, great work man. Cheers 🙂
