Auto populate attribution details?

Thanks for the plugin. Just wondering if it is currently possible to change the defaults in the Attribution Details setting for Title and Title URL, and Author and Author URL? I would like to change the current defaults from “the content” and “on this site” to a variable that would automatically populate these fields from the post being viewed. Is there a variable I can add that will make the defaults dynamic and contextual, rather than “the content” and “on this site”?
