[EXPIRED]How to show achievements when "Steam is learning about this game"

I learned this from some game community, and tested myself, it works, you can check my profile, it now has Hell Shooter achievements showcase. So this is how i do it: First, you need login steam on browser(i'm using Chrome), and go to achievements showcase selection, but DO NOT select any games, just right click on , and click "Inspect Element". Next, click the triangle before ,and right click on the second element, which is your first game, and click "Edit attribute":

Now change the number to "723350", and press enter to save it. This is Hell Shooter's appid, you can replace it with any appid you want to show achievements. Now go to your achievements selection, and select your first game, it will show Hell Shooter's achievements. And you need do this every slot.
