Bulk Edit
With Structure, you can quickly select multiple issues and edit them using the Jira bulk operation wizard.
To edit multiple issues:
Select the issues by clicking the small squares at the left of each item row. You can also select issues by pressing Space, Shift+Space, or another Keyboard Shortcut for selecting issues.
Click Bulk Edit.
This will open the Jira bulk operation wizard, which allows you to perform bulk changes on all the selected issues.
Each Bulk Edit operation is currently limited to approximately 200 issues.
