Ability to inspect a piece of media and see all Collections in which it appears

The Ask:
Provide a way to see all Playlists and [mod-edit: duplicate] Collections that a particular piece of media, Artist, or Album appears in. The feature is a way for a Plex user to easily view all Playlists or [mod-edit: duplicate] Collections containing an Artist, Album, or Track. The feature could also work for Movies and TV Shows, etc. [mod-edit: duplicate]

WHO: As a Plex Power User
WHAT: I want to have the ability to inspect a piece of media and see all Collections and Playlists [mod-edit: duplicate] in which it appears
WHY: So that I can curate my collection more efficiently.

The feature would need some entry point. It could potentially be located in the ‘…’/dialog button menu context. Initially, I thought it could become part of the Get Info option, but it could potentially warrant its own label/entry in the main menu, perhaps labeled “Appears In…”

The Problem:
Currently, when organizing playlists and [mod-edit: duplicate] collections, there is no way to know if a track is already part of an existing playlist or [mod-edit: duplicate] collection. I have to manually look through playlists and [mod-edit: duplicate] collections for certain items to see if they are where they belong, or missing, etc.

Current Workaround:
I whipped up a Python script that uses the API to build a .csv that I am able to sort and find the information I am looking for easily. However, the current workaround is not really feasible as a long-term solution.

Nice To Have:
It would be nice if a matrix of checkboxes could be displayed, allowing a user to essentially add or remove the entity to/from all available collections /playlists [mod-edit: duplicate] both collectively and individually.

Supporting Information:
The feature would need some entry point. It could potentially be located in the ‘…’/dialog button menu context. Initially, I thought it could become part of the Get Info option, but it could potentially warrant its own label/entry in the main menu, perhaps labeled “Appears In…”

Here is a visual example of where this option could be placed:
Appears In
In this example, the “Appears In…” option is added to the context menu, making it easy for users to find and use.

There’s already existing suggestions addressing the playlist aspects of your suggestion.

You should already see artist collections on an artist page in both Plex Web and Plexamp.
Corresponding collections are however not currently listed on album or track collections – so maybe let’s focus your suggestion on that section and comment/vote in the existing suggestions with regards to the playlist scope, in order to help us avoid distracting or cannibalizing votes.

Edit:
There’s one more related suggestion, focusing on listing all collections where an item appears on that item’s details page.
List the collections containing media (movies or tv shows) below their description

Makes sense. Will revise when I get some more time.
