How to freeze position and reset values to 0?

I have looked everywhere, i cannot find out how to freeze an objects position and reset values to 0. I need the position i place them in to be considered 0,0,0 so my code works correctly. I have it set to destroy object at a certain position which works for 1 of the objects, but not the others as they just instantly destroy since their positions r already at the set amount.

Create an empty game object at 0,0,0. Make the other game object a child of that object and then you can place it anywhere you want.
