Pallet utilization

Hello people!!! I have a situation and I can’t figure how to handle it or even if it is possible… the situation is:

I have a production order that will RAF 350 units of product, those 350 boxes are going to be grouped in 5 pallets with 70 boxes each.

¿How can I have those 5 pallets automatically created and identified in inventory when RAF the order?

Many thanks!!!
