Is it possible to convert nested Kotlin classes to a collection containing subcollections in Firestore?

Is there a simple way to convert something like this

data class Pet (
    val owner: Owner = Owner()
)

data class Owner (
    val name: String? = null,
    val email: String? = null
)

to a Firestore collection automatically?

This doesn't work for me:

val owner = Owner("Joe", "[email protected]")
val pet = Pet("Petty", owner)

db.collection("pets").add(pet)

It's not possible. When you add() an object, it is converted to a single document. If you need to create multiple documents, then you will also need multiple calls to add() or set(), each with the data to put in the document.
