Is there a addon “Mark/Resore” watched status?

I used to have this cool addon that would backup and restore my watched status. I know there is a addon called watch list but that is intrusive and kinda pointless for what I am looking for. (No offense to the creator, It’s just not what I’m looking for.)

I just need a simple program that has two options. 1. backup watched status, 2. restore watched status.. and that’s it.

I could swear I had a addon that did just this, but I can’t find it.

Does anyone know where I can find this addon?
