Performing of the stiffness analysis on dozens of load effects is not effective and correct. The best way is to prepare the load effects in a special way and avoid wasted time and disorder in the results. Three load effects will be prepared for stiffness analysis. Bending moment, bending moment and shear force interaction and all 6 internal forces. That is the correct load effect definition for stiffness analysis.
