How do we properly convert State<List<T>> to SnapshotStateList<T>?

The best I could come up with is this, but it feels stupid, I wonder if there is a better way.

val a: State<List<T>> = viewModel.collectAsStateWithLifecycle(initialValue = emptyList())
val b: SnapshotStateList<T> by remember{
    derivedStateOf {
        mutableStateListOf<T>().apply {
            addAll(a.value)
        }
    }
}

(note that when the original State<List<T>> updates, the SnapshotStateList<T> should also update)
