怎么对MDX多个量值进行汇总

现在需要在MDX的查询结果里面加入汇总行，因为涉及到两个量值，怎么样都能进行汇总

with
member [Dim Product].[Model Name].[ALL].[汇总] as
(sum([Dim Product].[Model Name].[ALL],[Measures].[Sales Amount]))

SELECT NON EMPTY {
[Measures].[Sales Amount] ,[Measures].[Tax Amt - Fact Reseller Sales]} ON COLUMNS
,
{
[Dim Product].[Model Name].children +[Dim Product].[Model Name].[ALL].[汇总]
}on rows FROM [Adventure Works DW] CELL PROPERTIES VALUE

现在只对Sales Amount汇总了，[Measures].[Tax Amt - Fact Reseller Sales]的汇总数是SALES Amount的，怎么样也对[Measures].[Tax Amt - Fact Reseller Sales]进行汇总!
麻烦各位大侠帮帮忙
