This idea relates to the ability to merge an unclassified document (sent via email to the documents@go2ppo.com email address) from your home page with an already existing document on PPO.
The benefit would be that a user can upload another version (example: approved version) of a document via the unclassified documents functionality and at a later stage merge the document with an already existing document allocated to a project.
This reduces the amount of time needed to first download the document in the email to ones local machine and thereafter locate the document when uploading to PPO.
