subclasses with inherited_resources?

I'm trying out inherited_resources and so far so good. However, one problem I've run into is that it's very difficult to customize inherited_resource behaviour in subclasses. Looking through the source I see it uses things like undef_method and class_attribute. For example, if I have the following controllers:

class ItemsController   inherit_resources   actions :new, :create

  def create     # custom stuff here     creat!   end

end

class VideoController < ItemsController   actions :new, :create, :show end

videos controller will not respond to /show because inherited_resources undefined it in ItemsController. One thing I tried was to call inherit_resources again at the top of VideoController, so it reloads all of inherited_resources default actions, but also over-writes the custom :create action in ItemsController

Am I overlooking something or is IR not supposed to be used for inheritance like this?
