Pair assets with briefs, check versions, carry revision notes. Every one is ready to run, and you can adjust it in plain language.
Send rejected creative comments to the designer's revision task.
Your designer gets the changes reviewers requested, tied to the rejected file version, with a link back to the approval.
Record your proof approval against the version you reviewed.
Your proof tasks show who decided, which file version they reviewed, and who takes the next step.
