"Other Recommender" question

After an Other Recommender submits a letter for the Common App, will I be able to freely use this letter for as many schools as I want? Or will they receive some sort of a notification for every single school that I add them for, and have to approve of the letter being sent? I know they probably can see the list of the schools their letter was sent to from their Recommender Account, but I’m wondering if they manually have to do anything for each school.
