PLATE STRESS AT TOP AND BOTTOM SIDE

Good morning,

I have to make question about STAAD Pro output plate stress ; in particular, I'm going to make a post processor excel file aimed to design concrete reinforcement of a slab according to ACI Code. Is It possible, for each shell, to obtain stress at the bottom and at the top side?

Is there a procedure to follow or a command that allow to have plate stress output (Mx, My, Myx, Sx, Sy, Sxy, SQx, SQy) at each side of the slab?

Thank you, regards
