I’ve seen similar features requests, but I don’t think this is exactly the same.
Since I have purchased movies on multiple platforms over the years, when using the “collect” feature, it would be helpful to be able to specify the platform, such as Amazon Prime, Google, Vudu, etc. instead of DVD or digital. Perhaps you could add a text field that could be filled by the user. The other option would be to list popular platforms, but then you’d have to update and maintain the list. If you did last the platforms, you could get really fancy and make them live, so when the user selected the platform they’re taken to the appropriate app.
