Perhaps I'm missing something, but is there a "Extract Field" refactoring (like 
https://www.jetbrains.com/idea/help/extract-field.html) for Kotlin yet/planned? I can extract a property but not a field. 
I'm looking for the equivalent refactoring seen in IntelliJ with Java:
 String result = doSomething(), then click on "result" and "Refactor->Extract Field" and I'm left with
String result; //as instance variable/field
and 
result  = doSomething()
