SQL Server Reporting Services Query COMPLETE WHERE CLAUSE PARAMETER?

Hello--I do not know if this group can help me with SQL Server Reporting Services ... but here it goes. I have a report built on a query and I want to be able to send a parameter (@theWhere) that is a string which is a where clause "(MEGLOMART_TYP_CODE <> 'XYZ' AND MEGLOMART_STAFF_SHORTAGE > 25)" these strings can vary depending on what columns the user selects and what operators they want to use. Generation of proper SQL for the where clause has been verified, I just need to be able to pass these, is there any way to do this...see example query below and how I was planning on using the @theWhere variable...

Thanks!
