So thanks to the recent Save The Acolyte petition. There is a feature that I just learned about that allows you to  request tv shows / movies to be added onto Disney Plus.

Here are the steps : 

Select "Submit feedback." 

•Then select “Request a Movie or Show.” There are only three boxes , so you can't choose all.

•Fill it in with one of the shows from this petition  , and Submit.
