Append responses to a single file when using Postman runner

[clairekardas]

First of all thank you for this amazing script. It's running well for me.

I saw you covered multiple responses in #7 already, but this creates a new file for every iteration. I am dealing with hundreds to even thousands of iterations and new files are not an option for me, so I would like to set the config to append to the same single file rather than use uniqueIdentifier to create a new one every time.

Is this possible with this script?

Thanks
