In JSD notifications are either on or of. According to the documentation, if email is switched of in service desk then a notification scheme in JIRA can be used to set up a custom scheme. This still does not work well for us because we need notifications for some transition (e.g. a request is waiting for customer input) and some do not (e.g. it is placed on the backlog or an engineer has started work). It would be so much more elegant if an admin could check for each transition in the Service Desk if a notification should be sent or not.
