Assigning a shared team to a plan (step 4 - define your capacity)

[Sara Watson]

When I get to step 4 in creating a new plan (define your capacity), it suggests a team based on the assigned board. However, the team suggested is not the shared team that was setup in the "Managed shared teams" page. I can delete it, but there is no way to add an existing shared team from that page. All that I have been able to do is to proceed with the suggested team (which has no linkage to anything) and once the plan is setup, go to Teams, delete the suggested one, and add the existing shared team. That seems incredibly inefficient.

1) Am I missing a setting somewhere to be able to show existing shared teams in the plan setup on step 4?

2) When making that change in the plan, I'm unclear what the consequences are to the Jira board when I commit to the change. Could that cause issues with my source data in the actual Jira board? 

Any help would be appreciated!
