Place one part of chocolate dough between 2 sheets of waxed paper; roll into 10x7-inch rectangle. Repeat with one part of cherry dough. Refrigerate both about 30 minutes or until firm. Peel top sheets of waxed paper from both doughs. Turn cherry dough upside down onto chocolate dough; roll up doughs together, starting at long side, into a log. Wrap in plastic wrap; refrigerate 2 hours. Repeat with remaining parts of dough.
