There are a lot of shows that half seasons between canonically numbered seasons, so while I can totally throw off the season count by making season 2.5 Season 3 and a Season 3 as 4, but it would be nice to have a way to either add midseasons or force the misnumber seasons to display a name of my choosing.
Having seen that thread after trying to avoid duplication, that is definitely what I would ultimately want, so I have moved my vote from my thread to theirs.
DTR’s solution helps eliminates confusion in my library in the meantime.
