Do you only have the 1 show or do you have both?
If you only have the 1 show I can see having this, & potentially the Episode ID option from my suggestion should do it, but how it’s implemented might make it an issue.
If you have both or for the Arrowverse
I recently discovered & have been using a Smart Collection to play all the Arrowverse shows in aired order. It’s talked about more in Watch crossover episodes of several series in-order. I actually made a Feature Suggestion to add a Unified Series option & was directed there. It’s not perfect, but especially if you set it to use each user’s Play State it works pretty well. I had actually stopped watching Arrowverse because it was too much work to watch everything together when you aren’t watching them when they air, but now I’ve gotten back into them & am enjoying them a lot more.
