How to change default dropdown option for Carrier when creating a shipment

We (almost) always use UPS for our shipments, so it would be nice for that to be the default dropdown menu option that is selected when we go into an order, click ship, and go to add tracking information.
The current default is ‘Custom Value’. How/where in the code would I go about changing it to one of the other carrier options by default?
