Scripting help: addSuggestedSpecifics / addRequiredSpecifics?

Claude and I are working on a complex script to help my personal workflow, and I’m wondering if the addSuggestedSpecifics / addRequiredSpecifics menu items (in the Attributes popup menu) are scriptable at all, either via AppleScript or JS internally?

What I’d like to be able to do:

  1. select one or more new listings I’ve created by duplicating old template ones, with their category set manually to the right category
  2. remove all attributes
  3. add required attributes
  4. (maybe) add suggested specifics (but probably not)

That way they will all be blank, and actually the correct keys for the category per the eBay most recent Category tree release, right?
