set all colored words into saved

Hi guys,
again, bravo for the work done so far. LR is amazing !

I am using it with Anki and it works well.

My request :
I wish I could click a button in the subtitle tab that would set all words above my level of vocabulary (they are colored in orange in my settings) in saved.
So that I can then easily treat the one I know in your new UI.

Right now I have to select one by one and it takes some time.

Many thanks
