A Playlist is simply a list of files, so that's not possible to do when looking at a Playlist.
However, you can achieve that effect in a view.
Create a new view, and select the Albums type from the dialog.
Now customize the view. Add a new category above Album. The type should be Expression, and under "Expression to group by" put:
FilePlaylists()
Now OK everything to save the view configuration.
You now have a view that mirrors the contents of all your playlists. You can customize that view however you want.
This is only a view, not a replacement for Playlists. You can't modify playlists here.
Have fun...
