Support settlement in columns due to creep and shrinkage in REVIT models

a model is modeled in Revit how can I input support settlement (support displacement) for columns at the foundation level. In SOFiPLUS there is an option to input the support displacement as free point load then choosing displacement as the load type. But in Revit there is only option for inputing forces in the analyze, load option there is no option for inputting displacement. Please let me know if anyone has tried it.
