I have the same use case, mowers come by or kids are playing outside. I have 6 cameras so my only option is to turn off all of them and remember to turn them back on. Rather than getting a bunch of separate notifications just update the existing notification to list all motions and if you click on it takes you to the ring event history (rather than live feed for a single event). The notification link would change from “snooze” to “snooze all”. Update the snooze dialog to include a checkbox for “All” which is unchecked for single notifications and checked by default for multiple notifications.
