Ability to align sprints with a fixversion

As a user, I want to utilize the fix version to define sprints so that I can use the many gadgets and reporting options available with fix version (e.g. roadmaps, release notes, statistics, etc.).
Currently, sprints are only available in GH; however, all of our backlog management, reporting, and dashboards are based on information Jira. Sprints are a fix version because they have start date, end date, and release date - release date is the date associated with the actual deployment.

Currently, it is also difficult to get a listing of all issues across sprints. I need this for software capitalization, release notes, and support needs. Therefore, having this aligned within JIRA for use in the issue navigator, I am able to get this information easily.
