Refactoring Inherited class structures in Atelier

I am having trouble finding/using the ability to refactor inherited elements from super classes.  In studio this was under the Class->Refactor->override menu.  I did note a 'refactor' option on the right click menu, but if you attempt to choose it the option greys out as soon as you get the mouse pointer over it.  Does this feature exist in Atelier as of yet?
