Is there any way to have incoming events in a Notable Events group assigned the ticket number that is assigned to an exciting event within the group.
As of ITSI version 4.0.0, you can no longer associate individual notable events to an external ticket (https://docs.splunk.com/Documentation/ITSI/4.0.0/ReleaseNotes/Newfeatures#Episode_Review_.28previous...)
You can now only take actions on episodes: https://docs.splunk.com/Documentation/ITSI/latest/User/Setupandrunnotableeventactions
