Sure, you can hard-code the filename in the config file if you want to use a single output file (rather than one file per iteration of the loop). Be aware that if you use repeating logic such as a ForEach loop, you'll need to set the flat file output to append rather than overwrite, otherwise you'll only get the data from the last iteration of the loop.
