The nearest thing I can think of is if someone local is notorious for fighting. It was not an official list but LEO all knew of certain people that could and liked to fight (and usually drink). If we got a call and dispatch was able, the first name of the person would go out with the call. More cars would roll if possible. Quite often there would be only two people on the road on Sundays. It was not uncommon for Saturday' nights escapades to flow over into Sunday morning. I had calls where a name went with the call. Your whole train of thinking changes when you know there is no backup.
