Add Countdown Notifications

I tend to get frustrated when permission to use an app shuts off suddenly. I’d like to be able to finish what I’m doing and mentally prepare to stop using the app. I think this will make it less likely that I pause my routine or delete the app. Can you add a notification feature to allow for warnings 10 minutes, 5 minutes, 1 minute, 30 seconds, etc before a routine starts? These could ideally be enabled by each user in the notifications settings.
