Variants for example: Option1+Option2 and Option2+Option3 (the first combination is interdependent to the second ) and Option4+Option5+Option6 (the third combination is independent from the previous two).
Custom Settings Per Combination

Stock Control Per Combination

Purchase Only Available Combinations
