Extending method in the base class

In the derived or the child class, is it possible to extend the method defined in the parent class.
I would not like to override everything that is already done for a given method in the parent class but would like to keep everything but add a little additional code.

I know that one can use super.method to call the base class method. Is this the only way?
For example, ‘e’/Specman had options to extend base class method in multiple ways.
