Email Digest

The News Email Digest does not provide a friendly subject line as the email gets delivered in Outlook to intended recipients. It starts with the name of the user who triggered the email digest following by …has shared with you xxxxx. Is it possible to change/configure or have somehow control on what comes up in the subject line? We got direct feedback from business users they would like the subject of the email to just include the topic related to the news not the name of the person sending the email digest. Thanks!
