Choose Edit > Paste. This pastes the new column objects in the same location as the original column objects. The pasted columns are the active selection.
Change the Support Set property from "below" to "above" in the Column Properties dialog box.
Note: If you do not change the Support Set designation then there are duplicated columns that do not allow the model to run properly. If you have copied a large number, it is tedious to delete the second column at each location (one by one).
