Create & Search Custom Fields
You can configure custom fields by type, enabling the easy search and display of multiple issues.
This issue type search/picker can be created directly within Jira's custom fields.
First, get started by navigating to Custom fields page, then create a new Custom Field using the CF Issue Picker Field Type.
Then, this new Custom Field enables you to select multiple issues and holding it's keys so that you can see these issues on particular Issue View page.
On Issue View Page, you will be able to view all the selected issues.
