Reporting Services :: Top N As Parameter In SSRS Report Populated By SSAS Cube?

I have an SSRS report that gets its data from an SSAS cube, and it essentially displays a list of students and absences. Everything works fine.

But the users only want to see the top N students with the highest absences. For example, today they want to see the top 100, but during summer vacation, they only want to see the top 5.

Is there a way to add this parameter to the SSRS report? So if I select "5" from the dropdown parameter, it will show the top 5 absences.

The query that I use to populate the report is something simple:

SELECT NON EMPTY { [Measures].[Absences] } ON COLUMNS, NON EMPTY { ([Dim Date].[Date Key].[Date Key].ALLMEMBERS * [Dim Student].[Lte Cell Key].[Lte Cell Key].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOSET(@DimDateDateKey, CONSTRAINED) ) ON COLUMNS FROM [Daily Cube]) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
