Embedded Timelines: Hide retweets from a specific user


I’m the webmaster for the Grafton School District and we are currently working on adding Twitter widgets to our high school website (see: www.ghs.grafton.k12.wi.us) for the principal (@GraftonHISchool) and athletic director (@ghsblackhawks). The principal primarily tweets educational related things, whereas the athletic director tweets game scores and results. The principal likes to retweet the athletic tweets so they go up on our school’s Facebook page, but this causes redundancy on our page. Is it possible to hide the retweets from the athletic director from the principal’s widget?
