Default JSD send customers an email when a request is created. We want to send the 'Request created' notification one step later when a request is accepted by our Support team. 
We've made a custom workflow (as you can see in the printscreen above) and also add an event 'Request accepted' to the notification scheme. In the workflow we changed the post function as is said in the article Adding a custom event - Configuring a post function to fire the custom event
How we can add a custom rule (the created event) to the 'Customer notifications'?
Or maybe there is another way to accomplish what we want?
Thank you for any help you can offer.
