[Revision requested for nonsense to buy time]

How does a seller prevent a revision requested to not be as a "delivery" as it will simply give the order another 3 days to complete?

A buyer can reason a revision for nonsense or to add an extra/addon which AFAIK is not possible at that stage.

Ideally a seller should have an option besides "Delivery again' to "Respond and close revision" without extending the deadline when order auto-completes.

Makes sense and does it sound logical to have this option implemented maybe or is there maybe another way to accomplish what is suggested?
