See the left image yellow box moves in 1 step increments - it moves horizontal at 1 step increments and once passed to end of the image (array) steps down 1 row and begins sliding through the image to the end.
One can specify step sizes... this image is 1 step increments.
So was thinking to have a feature like that - where the matrix could be populated that way - it might become very big though. Not sure ow feasible but wanted to think about it here.

I would need to see this in actual mathematics to understand what you want and how BlockArrays.jl fits in.
