Here you go. Changed the approach slightly, since I realized if you use "On Created", the target hasn't been set yet. Instead, I used a sub event with the "Pick all" system condition to reset the picked instances, then narrowed it down again from there.
Also you might notice I used a different condition than the System-Pick by Comparison. In the object you can also compare instance variable. I'm actually not sure what the differences between these two methods of picking are.
The other thing I changed was using the Tween behavior instead of Bullet, since you have a clear start and end point, Tween is probably more suitable.
Sorry if my answer earlier was confusing, I can make more sense with an example to work with ;)
