API: how to create a directory structure when uploading files?

I have a number of files with the same file name - only their respective directory names are different. Is there a way to include this path when uploading the files and creating a Classic Project through the API?

I know it's possible in the UI when uploading a zip file and ticking the 'unzip file' box. The folder structure inside the zip will be recreated in XTRF.

Any ideas on how to do something similar through the API?
