This would be useful in sending features to more than a single JIRA project. Our development teams are organized around services and platforms and often end user product releases rely on multiple JIRA projects and teams. It would be ideal to link features to a single consumer release without creating a product for every JIRA project
This is possible today. You can set up multiple JIRA integrations for your product. In the feature/release dropdowns, you'll have the option to Send to JIRA project of interest.
