Many users switch between multiple alternative of youtube apps which mean history ends up getting fragmented and impossible to just get a backup and move it to flow app.

By adding a mark as watched just in channel videos will help users to easily add it in flow history since we need to go through three steps to do the same thing and when you calculate how many videos each channels have it becomes a staggering long process.

I want this feature so that I don't have to see watched videos in my subscribed channels section because I still only watch videos their because flow algorithm doesn't seem to suggest good enough videos to make me use home section of the app.
