Every so often, I purchase an individual short that I already own as a part of a collection or from a live performance. I'm already using the "Digital titles you own are currently hidden" filter, but this doesn't take this issue into account. I watch the previews before purchasing, but that's not always enough for me to think "Hey, I've seen this. I must own it already... somewhere." and I buy it again. It should be possible to add flags to all titles so that repeats like this can be filtered out as well. Or, better yet, have the shorts still appear in the list with "This short also appears in a live feature you own." Something like that. I often buy a dozen or so shorts at a time and it's disheartening to discover I already own several of them.
