SOrry I don't have time at the moment for stuff like this.
If anyone is interrested in doing the changes: All you need is in _Tools folder. There are 3 batch files that do some copy stuff (I think it's explained in every step inside the batch files). Literally you only have to add episode ardyn movie files and folders to the batch files. You can find DLC files here
