Add "Bought" or "Audible Plus" flag

[fsafq41]

Is your feature request related to a problem? Please describe. No, just something that would make it easier to sort and work with existing library

Describe the solution you'd like Audible knows whether a book has been bought or is borrowed from the Audible Plus library. If such flag is available from their API, please could you add this tag to sort or filter on it

Describe alternatives you've considered The Audible app, but I'm avoiding that

Additional context None

That would be fantastic, and be able to filter and sort by Plus or Bought

I agree this would be a handy feature, particularly since I prefer to stream my Audible Plus files directly from Audible so the author gets paid. (I'm assuming it works like Kindle Unlimited?)
