I'm not sure that there is a ready solution for it. Maybe somewhere it is implemented, but not me. In theory this can be done as I described. In more detail: 1) You need the maps for eventin write conditions will be created events do not create objects. They will simply continue. 2) Create a trigger table eventin that is run when you add event and take it under the terms established in paragraph 1. If found then run the script. 3) Create a script that will recruit these events will take a number of object. Will make search in the table incidents/probsummary and will close action.
