I'm trying to work out how I give occasional extra time on devices for my child when she earns it. At the moment I have set down-time when her devices will be blocked. However, sometimes things change and I want to temporarily allow her extra time during her normal blocked time. But I want to be able to do this without having to change all those settings back and forth. Is there a feature I'm missing where I can choose “allow an extra 30 minutes, 1 or 2 hours” during blocked times, but it doesn't change all my settings I have now?
