Bulk Export Settings From the Docker

I do a lot of exports in bulk. It would be nice if the export docker would have a master setting for the export details for any file presently in the docker. As it stands I need to adjust the output size and resolution for each page of my document manually if it's not the same as the default document size. For example I have a 50-page document that needs to be exported in two different sizes, but each page would be the same size.
