Is your feature request related to a problem? Please describe.
You usually have "closing" completion for brackets and quotes, but not for raw strings.

Describe the solution you'd like
I'd like for the IDE to automatically close r' or r" with the corresponding quote.

Describe alternatives you've considered
Manually adding the quote.

Additional context
It works on Python, so this might be doable (try a = f"" or a = f'' - formatted string - on a .py file).
