It's not and it is also not possible. Scenes can happen at different locations and have different participants, depending on game play. For example, in scripting language, many scenes have id of location marked only as "current", which means they happen at the current id, the player is located. If you unlock such scene in dev console, it does not know what the "current" is. That is why scenes can only be unlocked through gameplay.Is there a way to unlock missed scenes with the dev menu?
If not, there should be.
