Hello,
1 - In the HikaShop backend you can manually assign a pack to an order while editing it.
It will pick-up or generate a serial for the order (or more depending the quantity) but you cannot choose the serial you want.
The algorithm will take the first available serial in the pack, or it will call the pack serial generator to create a new one.
Afterwards, the "order_serial_params" could authorize the storage of a serial_id in its structure so it will assign that serial to the order. But because it was not a requested feature and the interface would be confusing and complex, we did not add it.
You could access it and add it thanks to a custom plugin. But I would rather recommend the usage of the pack selection.
2 - Best would be to use a custom plugin so you will be able to override how the serial is displayed to the customer.
