How to have a displacement modifier vary it's shape within an array

Question

Total new on Blender cycles. I want to create a pyramid and for this I would like each stone to have a different displacement map. When I do one stone with the displacement map modifier it looks awesome, but when I put that into an array now all stone look the same. I tried using bump map with noise texture, and yes each stone have a different bump map, but it looks fake compare to the effect that I can get with a displacement modifier. Is there anyway to make the displacement modifier have a randomized texture so that each stone looks different, in its actual shape and geometry and not just in the bump map? Thanks alot

Displacement Modifier:

Edit:

As @Duarte Farrajota Ramos pointed out - for Array Modifier it's sufficient to just have Displace under Array without changing Texture Coordinates. Change is needed only for manually duplicated meshes.

This one is very simple (taken that you are using Texture Type other than Image Texture).

Just select Texture Coordinates as Global in Displace Modifier.

Note: I've forgot to add Array Modifier in this example, remember to add Displace Modifier AFTER Array Modifier.

For this example I've used Texture Type > Distorted Noise.

Micropolygon Displacement (experimental):

You can read how to use it here: https://wiki.blender.org/index.php/User:Maiself/Micropolygon_Displacement or just search for tutorials on the internet, there are a lot of them.
