Homing RPG should lock on to the zombie closest to the crosshair

The homing RPG is almost impossible to aim precisely since I believe it just locks on to the zombie nearest to you, so sometimes you can’t shoot at a big horde because there’s a vampire or something 2 feet away from you. It’d feel a lot nicer to use if it targeted the zombie nearest to your crosshair instead, so you can have more agency on what the rockets hit.
