Was Justine Bateman on Little House on the Prairie?

Justine Bateman is best known for her role as Mallory on Family Ties, a long running television show during the 1980s.  And Justine’s brother, actor Jason Bateman, had a major role on the Little House on the Prairie series as James Cooper, who was later adopted by the Ingalls family along with his TV sister Cassandra.    Jason appeared in 21 episodes of the show, but what about his sister Justine?

It doesn’t appear that she ever appeared on Little House on the Prairie, although it is possible she was on set at some point and appeared as a background extra, something that seemed to be common on the show with family members appearing as extras.  But it has not been confirmed she appeared as an extra.
