Nighhawk LAX20 - WAN to 4G failvover notification

Hello

I have a Nighthawk LAX20 as home router, using the 4G connection as a backup of my fiber Internet access.

Would it be possible to add a specific notification (via mail or Nighthawk App notification) when the router failover from WAN to 4G (or back from 4G to WAN) to inform the administrator that action is maybe required on the WAN access, and to ensure that he is aware that the router is now using 4G data (with potential volume limit)?
