As a Scrum Master, I need the ability to tie Sprints to specific "teams" to marry them together for Velocity charting, and other metrics.

Acceptance Criteria:

• During the creation of the Sprint entity, demonstrate that the sprint can be categorized with a "team" enitity (or label).
• In the board reports, demonstrate that the Velocity report has the ability to show only the sprints that share the same "team".
• On the different JIRA Dashboard "Wall Board Plugins" related to JIRA Agile, demonstrate that they can be filtered to only use sprints with a specific "team" categorization.

More detail:
I have multiple JIRA projects that represent different "Pillars" (i.e. different types of work). I have Scrum teams that each have a primary pillar, but that can perform work on any pillar during any sprint based on the company's goals at any given time.

Each scrum team, while potentially working on the same application as a different team, is it's own stand-alone body, complete with DB Devs, App Devs, QA-Testers, DevOps, and Product Owners.

The problem I have is, since teams aren't isolated to Pillars, we generally have a larger unified backlog that serves the whole department, and we use quick filters to show pillar specific tasks if a team is only going to work within a specific pillar.

I have a unique sprint for each team, in order to track velocity, capacity, and success on an individual team level. This is because they estimate on within their own team. Thus, Velocity should be unique among teams.

Unfortunately, Since each scrum board must include issues from every Pillar (i.e. Jira Project) since a team can work within any of them, the Velocity report shows ALL sprints, rather than just the ones for the Team I'm interested in.

I currently have no way to "tie sprints together". I could filter each board by a ticket field, but this would mean I need to manage that field for every ticket. ANNOYING. Thus, the Sprint label would simply this process.
