How to create user-friendly MDX parameters for MS Reporting Services?

In SQL Server Reporting Service, when I connect to my cube to create a dataset, in Query Designer I create my query with a filter. It creates the following MDX for me:

SELECT NON EMPTY 
{ 
KPIValue("KPI1"), KPIGoal("KPI1"), KPIStatus("KPI1") 
} 
ON COLUMNS, NON EMPTY 
{ 
(
[Create Date].[Month Num].[Month Num].ALLMEMBERS * [Create Date].[Hierarchy].[Month].ALLMEMBERS 
) 
} 
DIMENSION PROPERTIES MEMBER_CAPTION, 
MEMBER_UNIQUE_NAME ON ROWS FROM 

( SELECT 
( STRTOSET(@CreateDateYear, CONSTRAINED) ) 
ON COLUMNS FROM [ERP]) 
WHERE 
( IIF( STRTOSET(@CreateDateYear, CONSTRAINED).Count = 1, 
STRTOSET(@CreateDateYear, CONSTRAINED), 
[Create Date].[Year].currentmember ) ) 
CELL PROPERTIES VALUE, BACK_COLOR, 
FORE_COLOR, FORMATTED_VALUE, 
FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS

When I add this dataset, Reporting Services creates a parameter named CreateDateYear. When I pass a value like "2014" to this parameter I get nothing and I have to pass a value like[Create Date].[Year].&[2014].

How can I change my report to change this parameter for passing the value like "2014" instead of ugly and not user-friendly string[Create Date].[Year].&[2014]?
