Itesm not being removed from library when deleted from NAS

Hi, I have movie and TV series stored on a NAS and played via Kodi on an Nvidia Shield. When I add new files Kodi seems to add them automatically OK. However when I physically remove a video file from my NAS Kodi will not remove it unless I manually do a library clean up or play the missing file when i am prompted to remove it.

Is there a way that Kodi, on start up, will automatically remove missing file?

Thanks
