Cloning Custom Field Child Products

[TechitEasy]

Hi, I wish to clone a product and have it also clone the multi-variant custom fields as well, each have around 12 child products associated due to the way it works?

Is this possible? Having to price individually 12 different options is cumbersome to say the least.

Thanks a lot.

Edit: (Currently hitting clone clones the product, with custom fields but not the multi variant children)
