That's not possible due to draw distance, basically. Square made it so S ranks are drawn and visible on your screen no matter where they are in zone (due to early hunt issues where people couldn't target them to participate). A and B ranks aren't drawn on your screen until they're in range. Radar can only pick up the mobs once drawn, thus S are shown always while A and B are only within a set distance.
