Newman run with relative file paths in form-data for file upload

[frille70 (Fredrik Pejcinovski Svensson)]

@vdespa I have seen the replacement of path with an env variable in several places in forums. But I do not understand how to do that without the need of editing the exported json file manually and enter like {{pathVariable}} anyway every time you want to push your json to be used by for ex Jenkins. Because in Postman application, in the body of the POST request, you specify a file using a select file button, not with a path or env variable in written text. Or there is something I do not know about.
