[Mobile Notification] how to "cap" the badge number displayed in the app?

Does anyone know how to "cap" the badge number displayed in the app in any way? Let's say I schedule 3 notifications, and of course, any time a notification pops up it will trigger an app badge number increment, I want the app badge number always be 1 no matter if 2 or more notifications have popped up, I tried setting the notification BadgeNumber to 0, to -1 but it doesn't work, looks like the minimum app badge number increment is 1.

Any help would be appreciated!
