Tag pictures in Shared Albums

Issue as a Media Producer: When posting numerous pictures on the internet, it becomes challenging to recall which ones have been used from the camera roll. Wouldn't it be helpful to devise a system to mark or flag them for easier reference?

Solution: Implement a feature to enable sorting of "pinned" or "marked" pictures that can be toggled on or off. This way, it becomes effortless to identify which pictures have been utilized in shared albums. For instance, in a company with multiple contributors to a shared album, keeping track of used pictures can be cumbersome. If there's an option to mark them as "used" or similar, it would significantly enhance efficiency.

This feature would be especially beneficial for me when working in collaborative albums, like shared Instagram accounts, where there are thousands of pictures to review.

What are your thoughts on this idea?
