Question: list used names

Question:list used names

Udo 8 MapleSim
When simulating an electrical circuit I decided to eliminate a subsystem block but later changed my mind. Now I'm unable to use the same name for the subsystem block as before despite the fact that there seems to be no place where it is used. Always an error "The name blabla is already in use". Can I somehow list all the names and the places where they are used?
