feature "rewatch value"

Hi,

just a question: 

when customizing the private settings for a movie/series under advanced one can set the rewatch value which I find is a very great and useful feature. I would wish to add this field to my watchlist, but I can't find it under content options. Maybe I'm overlooking something?

Thanks for the input, Da Bao. 

At least I know, it's not only me.
