Variable product get dimension from parent

Hi,

I have a WooCommerce website with variable products and I have to set the weight and dimensions of my prodct for the shipping. Is there any way that I don’t have to set it for each variation? My variations are not impacting the weight or dimensions, so I would like to set it only for the main product and leave it empty for the variations. Actually, when I do that, my shipping methods are not working cause my variations haven’t any weight or variations.

Thanks!
