Question : Can we set custom exit code in Postman requests which can be returned by newman

[devsharma327]

Question : I need to return a custom exit code from newman in my shell script which can be set from Postman request based on some specific status code ?
In my requirement, while running a test collection through newman from shell script, I need to know by which status code does the test collection fails. One method I can think of is to manually set the exit code in test collection from postman, so that in shell script by using the exit code I can identify the status code by which it failed.
Can this be done from postman?

I have one idea - what if you set your info in a variable, configure Newman to export variables, read that (maybe simply process unique string presence in the exported file), then delete the exported file and use the result as exit code.
