The "upgrade to" feature should include digital movies

[Drew_Neilson]

I like this site's "upgrade to" feature that tells users which movies in their disc collection are available in a higher quality disc version, however it'd be nice if our digital collections were included such that the "upgrade to" feature would tell us:
1. which of our digital movies are available in a higher quality digital version (for example, movies that we own in standard definition and that are available in high definition)
2. which of our disc-based movies are available in a higher quality digital version (for example, movies that we own on DVD and that are available digitally in high definition)
3. which of our digital movies are available in a higher quality disc-based version (for example, digital movies that we own in standard definition and that are available in high definition on blu-ray).

When users add a digital movie to their collection, this feature would require those users to specify what quality they own the movie in (standard definition, high definition, or 4K), similar to how users are required to specify whether they own a disc-based movie on DVD, blu-ray, or 4K UHD blu-ray.
