2D Sprite Sorting along axis, how can i set the pivoty to the bottom center of my sprite ?

I am trying to make a 2D TopDown Game, the problem is that the character is sorting with the center of the sprites ive made. But i want it to be sort by the custom pivot point that i set in the sprite editor.
How can i achieve that ? The character and sprite pivot are set to the bottom but dont seems to impact the transluency sorting. The sorting priority of the two is set to 0.

Thanks in advance
