Hello fellow Odooers, 

I'm currently working on improving the shipping quotation process for our Odoo website, aiming for better accuracy and efficiency.

 I'm searching for a solution or algorithm that allows me to:

1. Specify how many units of a particular product can fit into a predefined box size.

2. Dynamically select and fill boxes based on the number of products in an order. For instance, if Box A can fit 10 units and the customer orders 15, it should place 10 units in Box A and choose the next appropriate box size for the remaining 5.

3. When one box is full, the algorithm should close it and start filling the next best-fitting box for the remaining items.

4. After the box selection and filling process, the algorithm should provide the dimensions and weights of all boxes used.

5. Integrate this information with our shipping carrier API (we use easypost) to generate an accurate shipping quote for the customer. 

Has anyone here tackled a similar challenge or have insights into a module, add-on, or custom solution that might address this? Any guidance or pointers would be greatly appreciated.

Thank you in advance!
