Heat oven to 450°F. Make pie crust as directed on box for One-Crust Baked Shell, using 10-inch tart pan with removable bottom or 9-inch glass pie plate--except do not prick crust. Trim edge if necessary.
Bake 9 to 11 minutes or until light golden brown. If crust puffs up during baking, gently press crust down with back of wooden spoon. Cool 30 minutes.
Meanwhile, in small bowl, mix blueberries and preserves. Spread in bottom of cooled baked shell. Refrigerate 30 minutes.
Spread with whipped topping. Refrigerate 1 hour. In medium bowl, mix strawberries and raspberries. Gently spoon over whipped topping layer. Garnish with additional whipped topping as desired. Serve immediately.
