Adjusting duration of WAN status email notifications

Hello all!

I have a peplink balance one core unit that we use to manage our WAN network currently. If there is any brief outage on any of our connected WAN services, if even for a few seconds or a min, we receive an email notification indicated such. I’m trying to find a way to control these emails so say we only get the notice after a 3 min WAN outage verses 30 sec to a 1 min.

How would I go about doing this? Is this even possible? Thank you!
