You can include custom fields in your report just as you do for the built-in properties. For example, if you have a custom field named "My Status" for use cases, you can do the following:
$listUseCases $ID: $MyStatus
If your custom field name includes spaces as above, you must remove them in your Word report template. Additionally, custom field names that begin with numerals or contain certain punctuation characters are not supported in reports.
Alternatively, you can report all custom fields without knowing their names or how many there are beforehand. This example shows how to list all custom fields for each use case:
$repeatUseCases Custom fields for Use Case $ID $Name: $listCustomFields $Name = $Value $endrepeatUseCases
