Incorporate client QC corrections into ManTra workflow

We use the ManTra portal to submit projects, get quotes, approve quotes, and download  project deliverables. After the initial delivery, the internal team proceeds with an internal QC step during which, occasionally, errors to be corrected are identified. With the current process, we send the proofed PDFs with corrections requests via email/FTP to the SDL project management team so that the corrections can be fixed in the source files and the project redelivered. We would like the ability to upload the PDFs with corrections to ManTra to keep the history together with the initial  project request and all the deliverables. Can this feature be added in the future?
