Good Afternoon,

I have searched extensively but cannot seem to find specific clarification to this question. When checking "R" class (or J, Z, P, X, etc. for that matter) availability is the attached "?N" class (JN, ZN, PN, XN, etc.) considered the same? So if R9 switches to R8, then RN9 will also become RN8 the same time?

Thanks!
