There are a few ways you can accomplish this.
If the points are very specific, for example set by hand, you could use an Array or spawner sprite.
-The spawner object way
The spawner object is easier, but more resource intensive. You simply put the spawner objects where they need be.
You could also use math, by taking into account the first random generated number to generate the second, but it all depends on what you want.
If this doesn't make sense to you or if you wanted to place the sprites yet another way, let me know.
