Add Drone Option, or change auto-deliver
As it is now, the options for Drones to do things are:
1) Get packages off shelves to containment/wrapping and put them back.
2) Take packages off vehicle and put them on the shelf.
3) Deliver packages from shelf to Delivery.

What if based on how delivery works, for those interested, there could be a research to unlock for those who like to hoard packages for promotion. Let it be "Place packages from shelf to vehicle". For those with a huge flatbed, we could have the drones load it up real quick, then we can back it up and manually load our trucks with packages. The purpose being so we can load the trucks with all but one so it does not auto deliver.
Having the drones load our truck is much faster than us doing it manually, which does same some time.

Or,
have a toggle for the delivery bay to auto-deliver at full or remain and wait for a manual send-off. This can be a default for new players, or make it a research to work on. Either or, whichever the devs feel would be best based on how the players are engaging with the game.

Some will find this useful. Some won't. It can be there for those who wish to use it.
Why wouldn't you want it to wrap after containment? Just curious
Ah, I see. I have a shelf dedicated to saving things and I put them in manually if I decide not to give them away.
