UNION в запросе многомерных выражений SSAS

Можно ли написать UNION в запросе SSAS MDX?

Например :

`SELECT
   {[Measures].[Sales Amount],[Measures].[Tax Amount]} ON COLUMNS,  
   {[Date].[Fiscal].[Fiscal Year].&[2002],
   [Date].[Fiscal].[Fiscal Year].&[2003]} ON ROWS  
   FROM [Adventure_Workenter code heres_1]  
   WHERE ([Sales Territory].[Southwest])  

   UNION

   SELECT
   {[Measures].[Sales Amount],
   [Measures].[Tax Amount] } ON COLUMNS,
   {[Date].[Fiscal].[Fiscal Year].&[2002],
   [Date].[Fiscal].[Fiscal Year].&[2003]} ON ROWS  
   FROM [Adventure_Works_2]  
   WHERE ([Sales Territory].[Southwest])`

т.е. СОЮЗ между 2 кубами Adventure_Works_1 и Adventure_Works_2
