How to group items together in Delivery note


My company ships goods that are packed in crates. Each delivery may consist of 5 to 20 crates. I want to create a delivery note that is able to show what items are in each crate, the item weight, as well as the gross weight of each crate of items. I also want to show the total weight of this delivery.
I know that I can use packing slips to help list out the items in each crate, but if there were 20 crates there would be 20 separate slips and I don’t want that. Is there a way to do so in the delivery note, where I can show the items belonging to each crate all in one table?

Any advice is appreciated, thanks!
