I am trying modify the automation schedule of creating shipments. The issue is that we want to give time for a person to put it back on hold and make changes before the shipment gets created. Also, if you remove from hold and quick process, there may be a timing issue.
So I added Last Modified On timestamp to the Process Orders grid so I could use it as a filter. The issue, is that it is set as read only in the value field, so I cannot even try working on it.

I know I could write a customization on create shipment from mass process to check that timestamp, but I would much rather build it into the schedule and not even attempt to process the record. Any help would be appreciated!
