In Commerce, Is there a way to auto-save a file attachment after it is selected?

Content (required):

We have some file attachment fields on our Commerce page. Our users are using Browse to select the file but they do not remember to click Save afterwords and lose their attachment. I was wondering if there was any way I could auto-trigger a save after the file is selected.
