Apply the discretize operator at each year

Hi RapidMiner community,

I am working on a project where I have to analyze the world economy by calculating the GDP and class them into 4 quartiles at each year.
I’ve used the discretize by frequency operator. However, when I apply it, it discretizes the whole dataset into 4 quartiles (that contains data for more than 60 years), and I would like to apply this operator and find the 4 quartiles at each year (so it will have different countries within the first quartile in 1950 and in 2000 for example).

Do you have any ideas how I could proceed?

Thanks for your time!
