Hi Jesus,
What you came across is a one-off case. I could just imagine the uncertainty that would be created if any Awarded event was made available for editing. Take awarding vis-a-vis signing some commercial document with T'c & C's. Post signing its only another signed document that can override the agreement that was signed earlier but does not hold true now.
Its more of an operational issue that cannot be governed by a tool mainly because its a one off and there needs to be a balance between impact on routine activities and one off issues while considering any feature to be built or not.
Regards
Vilas
