We currently have no plans to implement this. There are several reasons. 1) Event frames should not be considered a complete replacement for an alarming system as Analytics and event frames don't have all the requirements needed for an alarming system, 2) the logic to implement what has been requested in the UI would unnecessarily complicate the configuration experience and also manageability - when someone has to decipher what had been configured previously. As this time, we recommend that multiple analyses be used if multiple event frames are needed. We may reconsider this request at a future time and if so, we will change the status of this idea.
