Item Groups invalid variants

Item Groups invalid variants

I'm useing Item Groups. I set up 3 attributes with 2 options each. That would create 6 variations, but 2 of those are invalid, so I deleted the corresponding Items. This way the invalid combinations can still be selected, but generate message in the online store “Temporarily unavailable” Is there a way to pre-filter the attribute dropdowns based on what value is selected in the previous one, so that the invalid combinations won’t even show?
