We'd like the ability to set repeat intervals for SLA breach notifications.
For example, in an SLA rule, if the target definition is set to "Not assigned" within 30 minutes, an email notification would go out as defined in the Set Action section, and then continue going out every X minutes until the breach is resolved.
This was a feature that WebHelpDesk had, and would be helpful in Service Desk and allow for fewer SLA rules.
