[Feature] See when a song was added to a collaborative playlist

[iwant]

On normal playlists I can see the date of addition of the songs that constitute it.

However, on my collaborative playlists, I can only see the person who added the corresponding track.

Is there any (simple) way to see when the songs in my collaborative playlist were added ? (if not, I'll try to play with the Web-API)

In case it's impossible, maybe it's a feature idea for the devs.

Thank you.
