@mothered what method do you think that I can do then to SE a lot of books ?  Because I ordered 40 books now to do DNA but they will arrive in 2 or 3 boxes.

You cannot SE every box - just select the one with the least quantity and use the damaged package method.

And, can you tell me if DNA is possible when I receive 2 or 3 boxes of items (in same time or separately) at home?

You can only DNA multiple packages/boxes If they arrive at the exact same timeslot.
