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.

Ohhh didn't know all that.

Thank you PixiKel for clarifying! I thought it was something i could regulate on my end. Too bad.

Thanks again!
