Post-processing of models using solid elements

My question is related to STAADPRO. I'm searching for a feature of StaadPro (that might not exist) that would allow the evaluation of the forces present in a cross-section comprising more solid elements. For example, imagine a solid model representing a concrete slab supported by concrete beams monolithically connected to the slab. For the purpose of a manual design of the beams, how can one extract the Moment, Shear, Torsion and Axial of a beam cross section (rectangular or T-section). I'm asking this question because I found out in other programs it is possible to inquire these forces (for example in ANSYS).

Thank you,
