Multiple sprite instances and setting position to object

So I have two instances of an object called 'Block' and when they overlap an instance of another sprite (let's call it 'Area') I want the block to centre itself to the centre of the sprite 'Area'. (On overlap > set position to object 'Area' event)

However when two instances of 'Block' are overlapping two separate instances of 'Area' at the same time they both set their position to the same instance of 'Area' rather than to the ones they are respectively overlapping.

Any help would be much appreciated

You need to 'pick' an instance of area. You could try 'pick nearest' which means the Block will overlap the nearest Area. Or you can evaluate with matching variables if you want to have certain Block overlap certain Area.
