Insert generators allow you to automatically add issues to the structure. The issues can be the result of a JQL or text query, Epics or Stories from an Agile board, or an entire structure.

As you add and Insert generator you can choose from the following options:

Since the generators run every time you open the structure, the list of issues added by the inserter is always up-to-date. If some issues no longer pass the query criteria, they won't be added. Also, if you already have the structure open, the generator will be tracking the changes in your JIRA and add/remove issues as necessary.
