Import/export of .bak images

Hi,

please can you add new feature to WP Smush PRO?

Import and export .bak images - there can be import/export buttons to upload/download .bak images generated via WP Smush Pro. This buttons can be on post-edit-page and another one on media>smush for bulk import/export.

It can be great for people who wants top quality images but don't want to store theme on expensive hosting storage.

Thanks.
