Is it possible to get the 'Write to Data Store Entity' Smart Service to

Is it possible to get the 'Write to Data Store Entity' Smart Service to save a null value instead of an empty string on an NVARCHAR field in the database?

When updating a row, I want to set all fields to null in the database table if there isn't a value in them. Date fields are correctly being set to null in the database. However, for text fields, they are being saved as empty strings in the table. Is there a way for force the Smart Service to save them as nulls? I've tried to explicitly specify "=null()" in the value, but that does not work either.

Thanks...
