Creatures inheriting traits from parent class

[daemon13]

I am trying to create a creature tree for dragons, that goes from dragons to branch into metallic and chromatic, and then from there to the different colors/metals. Is there a way to have all of the traits for a certain dragon types to carry over when I create a dragon of a type. For instance, under the Black Dragon topic, I create a specific black dragon, I would like for it to automatically import/ populate things like element and alignment that is the same for all black dragons.
