# How to pre-assign a batch of stock to an order without choosing specific containers until later

When managing your deliveries, you can assign specific stock (such as specific kegs) to a delivery. Sometimes, at the point of ordering, you will want to choose which batch of stock must be used to fulfil the delivery but don't yet know which specific cask/keg numbers will be used.

Following the implementation of [this feature request](https://community.breww.com/t/allocate-a-beer-batch-not-a-specific-keg-cask-to-an-order-at-the-point-of-ordering-in-advance-of-assigning-stock-to-the-delivery/2796), Breww now supports this workflow.

To set the allowed batches to use, you should first add the product to the order. Then use the edit button:

Next, use the **Show additional options** button at the bottom of the window:

This will expand some extra options, and allow you to choose which batches can be used to fulfil the order:
