Editing the emit location on a sprite?

Hello! Im wondering if someone has any insight on adjusting the part of a sprite that the emit function generates from? I have a tall sprite that I want to have fire from the top grid of the sprite. Instead it shoots from the middle. Is there a way to change where the emit is located on a larger sprite?

Ive noticed similar function in proximity and ray cast. When opening a sprite to edit it, I can select the head or feet of the sprite and the ray cast and center of the proximity function generates from the point I clicked to select the sprite to open it. Does this actually function like this?

I also renew my call for rays/proximity etc guides to appear when testing in live mode inside the behavior screen. Is this feasible?
