ProfessorLogicMonitor has not shown any intent to add this sort of alert logic -- I know I have requested it for many years and seen nothing on the roadmap. It would be wonderful in many places, like "high CPU for N of the last M minutes", etc.
For events in particular, there is nothing if you use the normal event matcher. If you use Groovy, you might be able to leverage Collector Script Caching to track the events seen and only generate an event from the Groovy code if the your conditions match. I believe the cache is bound to specific collectors (not distributed), so if you use load-balanced collector groups I imagine it will end badly.
