Boxplot--how to label 75th percentile, mean, median, etc. this kind of statistics in boxplot

[superbug]

I used the following simple code to produce boxplot.

proc sgplot data=have;
   vbox score / category=year ;
   xaxis label="year";
   yaxis label="Score";
run; 

If I want to label statistics such as 75th precentile, mean, median, 25th percentile in the boxplot, (as picture below) how should a modify the code above?  Thank you!

This post adds labels but you can modify it to add the stats instead.
