Logging an SSIS task

I set up a connection in my SSIS program to a folder/file for logging.  When I run the SSIS program I have to go to the logging tab, select 'SSIS log provider for Text files' then select my Log connection in the Configuration String.  Is there a way to do this automatically?  Can I run a script that includes these settings?  Can this be done from a SQL Agent job?

Thanks.
