Wow, I had to dig deep in my architectural history terms for that one. We call it 'rustica' or 'brute work' here
With complex profiles it is very easy to add these sort of plinth finishes (hope that's the correct term). You can make the top part of the wall 'stretchy' so that you can just extend that as far as you would like.
Sometimes just adding this as a seperate wall on a finish layer works well too.
If you need very expressive joints on the blocks, this might be a lot of work for modelling!
