Can we have a tickbox in the Product ->Additions and Swaps to delete SKU's from Kits?

Can we have a tickbox in the Product ->Additions and Swaps to delete SKU's from Kits? If I clone a product which has variations, and then go to edit the file in excel, once i overwrite the sku's some of the old skus still stay on the product. Ideally like the way images works you can hit the "delete all images" instead have a button delete all SKU's or a tick box to remove the ones that we dont need and are going to replace. Thank you.
