How do I create a sprite relative to another sprite/tile?

I've got most of the variables worked out in my head but when playing around in C2 I can't figure out how to do this.

I want to spawn a sprite/tile and then once it's spawned it will spawn tiles around it. I need these tiles to be relative to the original tile though and grid snapping doesn't seem like an option haha.

Any ideas?

Sorry for the crude diagram.

an easy way its to use 8 imagepoints for the main sprite and position them accordingly then make an event that the main sprite creates 8 more sprites each for each imagepoint
