Notification after X minutes of normal state - How to?

Hi all,

How to clear an alert after X minutes that the device is UP again?
For example:

I have a network device with 40% of packet loss threshold configured. So, if the packet loss reach 40%, I receive the alert notificaton and thats ok.
But if the packet loss goes to 39% for only 1 minute then return above 40%, I receive the clear alert notification and another alert notification because its above 40% again.

There is a way to receive the notification of clear alert only if the device is in normal state after 10min, for example?
I know we can delay notification alert when the status is Down / Critical / Trouble but not about Normal.

Thanks in advance
