[2020] Either it is bugging or something but Blueprint variant in custom games is not showing up for me. Can anyone confirm? because read below what IW added in patch notes.

Just the title. Patch notes had this mentioned:

Blueprint variants of Gun Game and Gunfight can now be enabled in custom match advanced options for their respective modes.

Did anyone even check and found this option? I did but didn't see anything in advanced or well other options.
