I want to make a stage file without adding data the moment I make it.

Hi,

I'm having a problem with writing to a stage file.

I have an integration where I first make a stage file and afterwards I want to add new lines of data to it within a loop.

The issue is that the moment I make the stage file I don't want to add any data to it, I just want to make the file so I can append to it later. I want to add the data later in a loop. I can't figure out how to do it, it looks like you always have to add data when you make a stage file.
