How to edit multiple layers simultaneously with clone stamp brush?

[Artturi]

Hi! I have to tell, I didn't yet test this and I am coming straight from the Photoshop forum to ask if Affinity photo can do this. In Photoshop we can't. So, I have a document which contains multiple layers of the same image with different colors. I wanna create seamless textures out from those layers, but the layers have to be exactly similar to each other, otherwise, they won't work on the 3d program. I have attached here an image file to clarify the problem. There is the same image converted to normal map and to the height map. If one of those is even slightly different with other ones, the texture won't work anymore and is useless. 

So can I with Affinity Photo use the clone stamp tool to simultaneously clone stamp all the layers at the same time to make the texture seamless? 

 

edit: I was able to clone stamp 2 layers simultaneously, but what if I have 5 layers?

You would just change the setting on the Context Toolbar from Current Layer, to either Current Layer and Beneath or just Beneath depending on how you've got your layers setup.
