Pack and hold is a very manual process. The system should be able to recognise future despatch dates and place them in pack&hold status, including automated release on the despatch date.
It should also be expanded to include AwaitingReplen status orders, as replenishment is completed and occupies a pick location, which may not be released for a long period of time
Please also allow orders to be placed in Pack and Hold status and then picked and packed, but not despatched. That would be a much simpler workflow than requiring the order to be New for picking and packing and then placed in Pack and Hold status afterwards, which is how it works now.
