If you want to pack several varieties together, you can drag and drop the varieties you have created directly into the same packaging at calculation level via Shipping (white box). 

Even if you have several delivery addresses, you can easily add the varieties with different editions to the respective addresses. (click on the picture to start the animation again)
​

Similarly, you can also pack several products together. 

If you are on the order level, you can pack the products together under Packing & Shipping in the same way as, for example, several types. 

This can be useful if, for example, you deliver the products at the same time and only want to issue one delivery note with all products (Multi-item delivery note).

Please do not forget to define the packaging material. This is always defined for the first product of this order for all products. If no packaging material is defined, you can offer the product but not send it to production.
