Not really at the moment – although there is now an enhancement ticket to improve the Multipart Read so that it could do things like this. I’ll try and keep you updated about when it goes into development.
For now, another option would be to write the file to a “temporary” location and then have a separate pipeline that moves the pipeline to the final location. Then the API would require two POST calls, one to upload the file and the other that would take the file path and other things needed to write it to the final location that would “commit” the file.
