Description - First post so please forgive me if this has already been addressed! My thought is that Workfront could benefit UX functionality to take already existing documents/proofs (separately attached in a project or different project) and combine them into one document record.
Why is this feature important to you - Numerous times I see users upload multiple versions of a document that contain their own proof and accompanying edits. The ability to seamlessly combine these files into one document record will help cross-comparing proofs and provide one single reference point for auditing purposes.
