Programatic way of determining Data Flow Task Name

Hi,

I am planning to implement Lookup Errors in my Datawarehouse in such a way that the Lookup Error is redirected to an Error table. The table will have the structure of the source table + error column and code. I want to add two more columns to this table namely, the name of the data flow task, where the lookup was errored out and the timestamp. Is there a way of programatically identifying the name of the Data Flow Task, or should I harcode the name in a Derived Column Transformation befor the Lookup Transformation? Please advice.
