Passing Sequence Container name into the data flow task

I have been using SSIS for ETL testing purposes .For automation, I have created a generic data flow task inside a sequence container job. Now I want to pass the sequence container name to be used inside Data flow task(this is actually for logging).

I have tried below options:

I have created a pre execute event handler on sequence container where I store the SourceName into a user defined variable.But as soon the data flow task gets triggered, this variable value gets overwritten by Data flow task name.

Any idea how can I pass Sequence container name in data flow task name?

Any pointers are greatly appreciated :)
