Oracle PIVOT 行转列的单行小计如何实现？

Question

1、数据准备

CREATE  TABLE [StudentScores]
(
   [UserName]         NVARCHAR(20),        --学生姓名
   [Subject]          NVARCHAR(30),        --科目
   [Score]            FLOAT,               --成绩
)

INSERT INTO [StudentScores] SELECT '张三', '语文', 80
INSERT INTO [StudentScores] SELECT '张三', '数学', 90
INSERT INTO [StudentScores] SELECT '张三', '英语', 70
INSERT INTO [StudentScores] SELECT '张三', '生物', 85
INSERT INTO [StudentScores] SELECT '李四', '语文', 80
INSERT INTO [StudentScores] SELECT '李四', '数学', 92
INSERT INTO [StudentScores] SELECT '李四', '英语', 76
INSERT INTO [StudentScores] SELECT '李四', '生物', 88
INSERT INTO [StudentScores] SELECT '码农', '语文', 60
INSERT INTO [StudentScores] SELECT '码农', '数学', 82
INSERT INTO [StudentScores] SELECT '码农', '英语', 96
INSERT INTO [StudentScores] SELECT '码农', '生物', 78

查询结果：

行转列sql

SELECT * FROM [StudentScores] /*数据源*/
AS P
PIVOT 
(
    SUM(Score/*行转列后 列的值*/) FOR 
    p.Subject/*需要行转列的列*/ IN ([语文],[数学],[英语],[生物]/*列的值*/)
) AS T

执行结果：

问题：我想得到的结果如下，请问怎么可以实现呢？
