Automatically clear Stash events

Is there any handler available in Sensu that can delete a Stash entry automatically when the particular event is recovered from bad state to become a good state?

I need this because whenever we find any alert in Sensu we ACK it by silencing and put it at Stash. I want this particular entry to be deleted from Stash as soon as it gets recovered and cleared from Sensu events list.

Thanks,
