How do I change the Third person aim to aim straight down

Right now when you look down, the cursor is aimed down and a bit to the right due to the offset the camera has from the head of the player, so it looks over his shoulder.

I tried fiddling with the camera and the camera boom but to no avail, I could never get him to aim straight down while also maintaining a healthy offset for normal movement.

Is there a way to set the straight down aim target or aim the camera without it being finicky?
