Lets say I have a shader with a clean white tile. Then I use it on a wall and tile it a few times.

I also have a sprite with numbers.

Now, is it possible and if yes how. To put a random sprite number ontop of the already tiled texture.
Example:
I am pretty sure this can be achieved with shadergraph, but I am hardly an expert and I really dont want to spend a month or more try-erroring my way through...
