Can someone dev that vehicle turret can shoot full automatic on manual control?

Still playing stable 0.C, the vehicle turret which it has machine gun turret can’t shoot full automatic on manual control aiming, only work if player set the turret to full automatic on auto mode

Can someone dev it please? Can’t standing those turret only shoot full automatic on auto mode, it just waste ammunition and shoot unnecessary target, shooting all over the place if attacking group target.
