Invalidate certain variants (don't require all variant possibilities)
After setting up variants, I was hoping there would be a way for the drop down variant menus on the product template to hide variants I'd never have. For instance, if I had colors X, Y, & Z, and sizes 1, 2, & 3, but color X would only ever come in size 1, if I chose color X on the drop down the size options in the next drop down would still show size 1, 2, & 3. I wish when choosing color X, the only available option for size would show size 1 and not size 2 & 3.
