Mapping Defaults - Option to toggle default settings for mapping listings

When mapping listings can we have the option to set the default toggles. We are forever deselecting the toggles under 'Copy the following from the listing to the product: Images & Custom Attributes' as these two buttons are set to default as 'Yes' but as we don't want to copy the images and attributes across to these products as a default we have to constantly deselect these before mapping the products.
