Kodi filter for unwatched

I’ve added Kodi and it works well, is there a way to add an option to filter the library via ‘unwatched’.
Obviously if you have a large library it can be a pain to scroll through a massive list trying to work out what you haven’t/have watched.
In the kodi webpage you can filter by this and I know it has the little dot thing on the left but that’s not enough to make it convenient.
