Is there a mean to specify specialization-genralization (inheritance) of actors in UML?

actor

I am just starting to use UML and have came to the following question:

Some actors clearly are specialized versions of a natural entity. For example I've got Administrator and User actors which are clearly nothing but different roles of a user, Authorizer and Dispatcher which are services (and are going to be implemented this way). Should I just ignore these facts while modelling actors and use cases or specify it some way? I think I could make good use of such a specification to facilitate code generation.
