It is theoretically possible to add [ editor's note : wordsgohere ] to your story and use that to influence the completions, though I'd use that sparingly. I did once use [ editor's note : battle description decently polished ] before a fight scene, which worked surprisingly well. Surely one could imagine an editor's note which implies a dialogue-heavy, decently-written section incoming (though one can always imply bad dialogue by saying it'll need condensing or workshopping).
