Ports can be added to multiple selected objects at the same time by selecting multiple Objects before selecting port type to add
Naming Ports (3 methods):
1) To name a net select the port and Place the new name in the context panel window designated Abbreviation as shown to the right. Name will appear as shown to the left.
3) Ports connected to named nets may automatically be named by the net name by checking the "Automatic Naming from Net" check box in the context panel when the port is selected as shown to the left here. If the nets is coming from an output port that is also not named both porrts can be named at the same time by selecting both and checking "Automatic Naming from Net" This can many times save modeling time
