NFHS (US high school), and presumably other leagues, use a dual officiating system (two whistles).
I would like to be able to specify what system is being used. Technically, putting the other official as ‘assistant’ is incorrect.
Likewise, VAR which I think should be seperate from ‘observer’ and ‘4th official’.
Also integration with Trends.
dual would also help when using REFSIX for futsal….until there is a futsal mode. :)
