Attributes combination like prestashop 1.7

I wrote this before but no answer.
In presta shop you can create Atributes grups with many posibilites adn in product you can chose some, not all. And for each one selcet different price. And in product page you see only specific attributes combinations.

For examle you have plenty screws and each screw has a size property. So you create Size attributes group where you adds values. All sizes for all screws.
But when you create product you chose some for specific product.
The problem is that on product page you can select all sizes no only selected for this product.
How shows only specific attributes combination for product on the page ??

I totally agree, it's really annoying to add the combinations one by one, or add all the combinations at one also not needed ones
