In my controller I've got the destination columns and the origin fields for specific data entered in my create function. However, I've got a few default values in here, like below:

```
    $shipment->shipment_billing_status = 1;
    $shipment->created_by = $user_id;
    $shipment->cn_billtoName = request('cn_billtoName');

```

As you can see `$shipment->shipment_billing_status` default value should always be 1. However, in extreme cases, I would like a user to be able to choose (if they need to) between two checkboxes, titled "No Settle" and "No Charge", or their values being 2 and 3. 

So in those extreme cases, I want a record to absolutely go to 1 if the "No Settle" or "No Charge" checkboxes aren't selected.
