We have callouts for "enemy spotted A" or "a lot of guys mid!" but there's nothing to specifically state that all 5 have been spotted. Something like "they're all B!" would be a great addition to the game because having 100% certainty that every enemy is in the same spot would free up people from other parts of the map to rotate into them instead of anchoring. Currently the only way to know is to look at the minimap and count the question marks, which can distract your attention.
