pivot table - Expression to create SSRS column dynamically -

-

i need expression take existing column , recreate column on , on before column/s column name contains either "monday" or date of column falls on monday.

the reason need expression repeat header column in pivoted report pivoting start/enddate parameter. if user selects run report month, should 31 columns (for each date/day) , header repeating before every monday.

make sure dataset contains dates in date range. if not create date table , cross join it. don't pivot results, let ssrs bit. once dataset has dates, can use matrix in report , drop date colum column group. give 1 column each date in dataset. i'm not @ pc @ moment if need more help, show example of dataset , i'll put quick sample report.
