Feature request

This is a great plugin and it works for me exactly as advertised, thank you!!

I always wondered, why there is no easy way to run a command to scan by demand all the pages/posts against the existing media library and update the attached/detached status the media library files instead of guessing and checking manually? Is it possible to add this feature or maybe it exists already somewhere?
