custom checkout fields editable in admin?

hy,
i created some custom checkout fields according to https://docs.woocommerce.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/ using the woocommerce_checkout_fields filter. now it would be great to have these not only showing up in the orders admin view, but also editable like it is possible for other fields like addresses.

is there a way to add my fields to this existing edit-functionality i am missing, or do i have to create input fields again for the admin-view and save the post meta for myself?

thanks for your help,
matt
