Is there a function to tag a star

[loveakirayui]

As the title state is there a function where you can tag a star and when you log in are alerted of anything new posted about them? Like if I find a new girl that I really like and would like to see more of, instead of writing her name down or trying to remember it I can tag her and cum back to her later. If there is not already such a function THERE SHOULD BE!
