Is it possible to go beyond 63 stacks?

As far as I can tell, Spritestack seems to be capped at 63 stacks, and there doesn't seem to be a way to go beyond this. Since I'm trying to create assets, I'm hoping to keep the relative voxel count between objects consistent for the sake of aesthetic and consistency. Is it possible to circumvent this, or add in the ability to go beyond 63 stacks in the future? It makes creating taller objects rather unwieldy.
