[Request] Add an option to unwatch/remove the latest activity on a movie/episode

I couldn't phrase it properly in the title, but what i mean is the ability to either do:

1. unmark as watched (already exists), or

2. remove the last watched activity (add this feature)

I use stremio and sometimes i dont complete an episode in one sitting, so when i come back later and finish the episode, its is marked as "watched" twice.

So i want the 2nd option ("remove the last watched activity" option) to make titles that are watched twice to be marked as only watched once; titles watched thrice to be marked as watched twice, and so on. Thank you
