Hello, There is a point in the program that I cannot solve, and I will try to explain it with another example to simplify my own problem. Let's consider a 3-span silo carrier stand as in the attached picture file. 3 silos will sit on this stand. We will create combinations from these silos when they are full or empty. "silo-1" "silo-2" "silo-3" when I create loading status as "silo-1" "silo-2" "silo-3" instead of using the "G" loading status that the program automatically assigns while influencing the loads of the silos on the support points on the beam. I see that the loading conditions are not included in the earthquake calculation. Is it possible to add "silo-1" "silo-2" "silo-3" uploads to the mass source tab as in Sap2000?
