how to offset the outline when applying one?

I would like to know if there is a way to tell the outline where to land.example: when I apply outline to an fill ,half of the thickness goes on the top of the fill and the other half is outside the fill, I was wondering to know if there is a way to tell the outline what percentage of that covers the fill(overlaps) and the rest of it goes outside of the fill?like if I am applying 4point outline so I can say I want 0.5point to overlap the fill and 3.5point to be in the outside

I hope this make sense.
