Display author instead of source?

Hello. I am finding the plugin very useful. The only issue is that when I display the source it just shows my feed name (my feed is already aggregating other feeds: http://www.inoreader.com/stream/user/1005627960/tag/user-favorites). Is it possible to display the Author username of the posts instead?

Thank you for your time.

Michelle
