Product Inventory, Packing List with Group of element

Hey there,

Trying to setting up an Airtable Base to manage my product Inventory. I sell and install device to irriguate fields, each device have a default quantity of piece that I use for earch order.

To help My employees I’d like to create Packing List stored by date and client with Airtable. I managed to do so but only by referencing each piece at a time (one device got many different piece). To prevent errors i’d like to create a categorie where I can set all piece and default quantity for one Device Then on my Packing List simply add One device to pack and all the different piece will be added to the packing list with their default quantity at once.

I didnt see anything to help me with customed Group where I can add Piece and Quantity to display every with one click.

Thanks for helping,

Here is my Group Table where I displayed all the piece from one
group:

And here is what my packing should look like : but i’d like to add all the element by using the “Centre Point” Categorie once
