Can we assign other load case like nodal and element load along with the specified displacement of support?

In the case of "Specific Displacements of Support," the program internally creates the nodal load that would create the required displacement at that node/support but at the same time, it also limits the displacement of that node by the specified value. For individual load cases, there would be no issues in the results, but if another load is considered along with the specified displacement load, the overall displacement of that node will be equal to the specified one. In other term, we can say that that node will become rigid in a specified displacement direction after that displacement. 

Let us take one example to understand this procedure more clearly.
