When a new JIRA project is added to a plan in Portfolio it would be nice to be able to add that plan's cross-project releases to the new project.

At the moment the only way to do this is to delete the cross-project release and recreate it. This destroys the release across all the projects and removes it from any issues it was attached to, considerable time is required to then reattach those issues to the new cross-project release.

We have a large number of projects in JIRA and it's more managable to add them to a plan one-by-one, however this is impractical if projects have to be in a plan before cross-project releases are created.
