Create and link multiple JIRA issues per story, one for each skill

The use case we frequently have is:

• 2 or more team members should be scheduled to work on one task, at the same time (if possible).

In the same way that Portfolio can create and link one JIRA issue per stage, it would be great to have one issue per skill, with one dedicated assignee each. Portfolio should then try to schedule these at the same time, just like it does for Epic bundles now.

What we do at the moment is create 2 stories/issues, and put them into the same release, and hope they get scheduled at the same time. This kind of works, but puts some wrong functionality in the release stream.
