Sorry for what might be a dumb question to all RS owners (new to Audi ownership - from the M division dark side

Ive managed to damage the upper section of the rear bumper corner and I'll be taking it to the bodyshop
My question: is the upper section rear bumper skin the same as a regular avant with a different diffuser/exhaust hole section?
Or is it a completely different part?
I know someone who has a mint upper section in the right colour and was hoping It could be a case of just swapping the lower diffuser section over?
Many thanks
