Changing shots that are fired not the gun

[Eng]

My question is about export_descr_unit.
Every missille units hase a weapn and a shot

stat_pri 20, 3, musket_bullet, 45, 20, missile, missile_gunpowder, piercing, none, musket_shot_set, 25, 1

so the question is if the color red is the gun and the color blue is the shot, is it able to cahnge the shot to a balliste shot? so that lets say camel gunner will shoot the balliste javelin
