SSIS Expression to handle NULLs in multiple columns

I have an OLEdb source that has some nulls, it has 50 columns and im trying to extract the rows that have NULLs to Bad data destination, the expression that I had for the conditional split is 

    ISNULL( [StudentName] ) == TRUE

but that means I have to repeat it for all the columns that I have and I'm wondering if there's another way to handle this. especially since I have multiple tables to process. 
Thanks
