Emails should display "From" instead of "From/To/CC" in document section

Didn't know if this was by design, or if there is a setting/option for this, but in the document section of a client in Ichannel, when we click on Emails, one of the columns says "From/To/CC", but only lists the From. Is there a way to show the To column separate or just list the To instead of the From?
