[6.5.3] Do Not Send Disk Usage Notifications on Every 1% (percent) Increase

How can I configure Disk Usage Notifications to be sent evey 2% or 5% increase instead of 1%?

It is quite annoying to get a notification for each disk on every 1% increase.

Deleting everyday tons of notifications for disk usage from my email and Slack account.

Notifications for disk usage are important, but not at every percent. On warning and critical threshoulds should be enough to generate a notification.

If not so, one should have the possibility to chose how how often to generate the notifications on every 1%,2%,3%,4%,5%,10% and so on...
