Backup with FTP

I create a new ssis project. I add the backup database task and the FTP task.

I have everything working except:

I created the bak files like "databasename01010.bak', using the default method.

Problem is when I go to the FTP task, it wants a real bak file name. I will never know the name as it is created during the backup task.

How can I get the FTP container to use a *.bak?

I'm new to SSIS and would like to aviod using variables if possible.
