I agree with
@urgodfather
Currently his statement is safest and most efficient way. However the more I think about it,
@magicstars this is a good suggestion or feature. I think for now the only way to achieve what your looking for without attempting to modify an existing panel would be to attempt to utilize some existing Social Service like Discord or Slack with an area that is ONLY for reporting down channels. Then creating a bot, or use one of there apps that enables Push Notifications for that specific room. However be prepared if someone wants to be a dick they could really start blowing up your phone.
Could be pretty easy to set something like that up, however then you have the challenge of getting the user base to actually get into/USE the reporting room.
