Common Case Class Variables

Does anyone have any thoughts/better way to handle common fields that cross multiple case classes...for example I have the following case class;

case class Customer(
    name: String,
    refId: String = ReferenceIdGenerator.generateRefId("CUSTOMER"),
    createdAt: DateTime = DateTime.now,
    updatedAt: DateTime = DateTime.now,
    id: Option[Long] = None)

The last four variables are repeated in every "model/domain" case class in my example application. Is there a better way to remove that common boilerplate code?

One thought would be to create a "common" case class and at least the boilerplate code is limited, for example;

case class CommonFields(refId: String...etc)
case class Customer(name: String, common: CommonFields)

Thoughts?

Yes, this is the correct solution, assuming this works well with whatever you use to interact with the database. If you are using Slick, see also Extending SLICK Tables in a DRY manner.
