Thanks very much to both of you for the detailed responses. I'm afraid this is now beyond my expertise, I'm actually just setting up my home pipeline, which is not meant to be nearly as robust as a full studio pipeline would be. That being said, I do want to eventually put in something more robust and learn more about the execution of making a more formal pipeline, so this will be invaluable at that point. Much appreciated! For now I'll stick to the absolute path as a quick fix.
