Is there a way to define a new spell component type? I've gone through all the tabs in the editor, and I can't seem to figure out where to add that. Specifically, I'm talking about adding an entry to the list in the Editor where on a spell you click the Edit button and get the list of:
Verbal
Somatic
Material
etc.

I'm not looking to add text to either of the material component or focus component, but to add a new entry to the checklist.
