I told you how you can forward a unique identifier over a function.
Wasn't that the question?
This helps to pick a specific object, out of many.
If you only have a single sprite instance, then there's no need to forward this information. In that case, just apply the re-positioning directly.
But if you have multiple instances of a single sprite, this is how you can pick a specific one, over a function.
Otherwise please share your project (or an example file) and give a more detailed explanation of what you're trying to achieve.
If you're just trying to keep multiple objects at relative positions to another sprite, use the hirarchy feature as described by dop2000. But that has nothing to do with a function.
