Print multiple 2x2 pictures

I used to be able to print multiple 2x2 pictures in one sheet from iPhoto by selecting the desired size and then selecting multiple prints per sheet. It used to be a very simple procedure, the software chose how many copies it could print based on the selected paper size, and I had my pictures printed in a breeze. I am not sure what changed in the software, but I realized today it does not work that way anymore.

I just spent a couple of hours trying to get several 2x2 pictures printed in one single 8x10 sheet in order not to waste my photo paper. It took me a long time to figure out how to trick the software by duplicating the pictures multiple times until I had 15 copies, then selecting them all, clicking on print and then selecting Custom size 2x2. The problem is, this is not a straight forward solution, as it used to be on previous versions of the software. I refuse to believe Apple has messed up by getting rid of what used to be a useful feature of iPhoto.

Is there any straight forward way I am not seeing?

I searched online assuming there would be a very simple, readily available procedure that would make me think "of course!" but all I found were outdated posts that explained it the way I used to do it several years ago, or silly options such as "drag and drop to desktop, open in preview and then print from there". This can not be Apple's vision on how we are supposed to print our passport pictures, there MUST be a better way! Please enlighten me!
