I'm adding this answer to clarify the accepted answer because it's too big for a comment.

The general pattern here is that you can use any combination of the Scope Functions available in Kotlin separated by the Elvis Operator like this:

?. {
    // code if not null
} :?  {
    // code if null
}

For example:

val gradedStudent = student?.apply {
    grade = newGrade
} :? with(newGrade) {
    Student().apply { grade = newGrade }
}
