For the combination of actions in the ultimate and the serviceability limit state, you can select various design situations according to the standard (for example, ULS (STR/GEO) - permanent/transient, SLS - quasi-permanent, and others).
Furthermore, there is the option to integrate imperfections in the combination and to determine load cases that should not be combined with other load cases (for example, construction load for roof not combined with snow load).
