Make all movies ‘watched’

Hi again,

I have installed my HTPC with Kodi 17 from scratch.
Now I want to make all movies and TV-series ‘watched’
because only a few of them are ‘unwatched’.

In Kodi 16 I could rightclick the source and make all
‘watched’ or ‘unwatched’. I can’t see that feature anymore in Kodi 17.

Have I missed something?
If not, is there any workaround?
I have mySQL installed, can I change it directly in the database?
