Unity - Tiling of a material, independen of its size

I am using Textures and Materials to tile my sprites, for instance when building a wall in my game.

The problem with this is that everytime I resize the plane or size of my game object I have to retouch the tiling property of the material.

I have asked around about how to solve this, and they told me to write me own shader, but after reading around a little, that seems quite a deep and long topic, to solve this small issue.

Would anyone know a way to solve this issue, or at least recommend me a shader that already does that ? (and if possible a small explanation on how to use it).
