Woocommerce never save shipping address on checkout page

By default Woocommerce saves the billing and shipping address on the checkout page.

I am searching for a way to prevent Woocommerce from saving the values in the shipping address. So all the fields in the shipping address should be empty.

In another thread I found a partial solution. It works great, but it also makes the billing address empty:

add_filter('woocommerce_checkout_get_value','__return_empty_string',10);

Is there a way to do this only for shipping address?

Big thx!
