Please add a Profanity filter to Roku

Please add a profanity filter to movies/shows available using our Roku device.  We have many apps through our Roku device and absolutely love them.  I would be happy with a profanity filter using the closed captioning data.  I know it wouldn't be 100% accurate but it would help reduce the profanity.  I understand some movies would contain a great deal of bleeping, but we probably wouldn't be watching those anyway.  We would just like to omit the profanity on PG movies or PG-13 movies/shows.

Thank you for your consideration.
