The ability to add cards at 0 Challenge Rating would make this possible, which also adds the additional functionality of making 0 CR obstacles that are present in the scene.
Currently, the alternative is to add in an asset that can be used to solve these challenges without actually making them challenges. For instance, if I want to include an NPC for players to make note of, I can make him a 1 Challenge Rating obstacle, and provide players with a "Dialogue" asset that they can use. Then, the neutral option for a scene that the narrator describes can be what they want to occur after a dialogue with a friendly party. So long as players understand not to use the Dialogue asset to solve challenges outside of these psuedo obstacles, things could be ok.
