This seems like such a simple thing and it is so aggregating that the option is not available! Please add "Ship Date" as an option to change in the Bulk Update. Currently, this can be done one order at a time in the Configure Shipment box but it is literally impossible to do for 100's of orders!
We print out our labels the day prior to pick up by Fedex so that the orders can be processed and then be ready for pick up the following morning. We run into an issue with Fedex where they have to re-label all of our orders because the ship date is incorrect. They have to re-label 100's of boxes just because we are unable to bulk update the ship date! (something we can easily do through fedex.com. Please fix this!
