In one youtube documentary series they re-did first 10-15 episodes to match the same style and quality as those that came after. Both old (original) and new are available for watching, though.
I was wondering if there's a way to add multiple episodes under same season and episode number? Or would currently best-fit place for this be under Specials? I don't think new versions should replace original ones since they're years apart and content is different (visual content, not audio). So, would it be okay to add the new versions under Specials, or maybe just add them in same Season 1 but under later numbers?
