To imagine here a pic

as you see the first chest at the top is just for testing, I put myself there the stuff. But the second chest is the imporant part. I want to put there only 10 irons and 10 steels because If I do not limit it.. it will insert only steels because of so many steels.. but I need both.
I know I could do two ways and use filter inserter but it would take more space.
I also chcked with filter (instead of blue inserter).. but it would be nice if filter insert gets per item a condition.. this would be amazing.
