@circleconstant314 sorry I didn't understood it before, but answering your question I really don't know, I apologize but I'm not really an expert on setting, as a matter of fact this is only the second time I created a sudoku, I just thought of this constraint and did it, after I study more about it I may be able to answer you properly
