I have used the search function for this and I think it hasn't been thought of.
I think that you should be able to choose a rating from 1-5 on different items of IFS such as headphones and amenity kits. This is because most airlines have better headphones and amenity kits in First Class than in economy. Currently on AE they are just the same. They would have different prices so it would be more expensive to give better quality items.
