Parameter for automatic / percentual voxel size from max height/width/depth

It would be nice if the program would get an option to define i.e. the max height of the model and calculate the voxel size based on that.

I am currently facing an issue where the program kind of just hangs for hours (my model is 14382mm in depth) and the voxel size i calculated gives me wrong results in the program - if it ever finishes to process.

Additionally, a % parameter instead of a static size would also be neat.
