It is possible to update an already submitted request in three ways: a) you can update the metadata that are submitted as part of the request, b) explicitly ask an internal module to re-process its input and provide an updated output or c) ask for a full re-process, in which case all components are re-run on the original audio file.
This functionality is accomplished by a PUT request to an existing process using the unique process id (pid). Notice however that requests which have not been completed can not be updated. Also you can fully re-reprocess requests that you have submitted using the storedata option, so the original audio is available on your data store.
