With the release of the recent Service Desk (v 3.3) the option to customize a Service Desk template was added and users are able to add specified variables to the template as described here.
There is however no way for customers to add values coming from custom fields or other fields not in the listed ones in the documentation above.
Can a feature like this be added to the Service Desk Mail customization or if it has been added, can it be documented?
There is no function that fulfills the above from our test.
