Assign multiple shared teams to an issue

As an PO I want to be able to assign multiple advanced roadmap shared teams to one issue.

We have multiple teams that are filling a supporting role one more than one issues (e.g. Initiatives, Epics) These teams are required to fore-fill certain actions for these issues.

I don't want to create a plan based team for every plan we need this team to be working on a this won't give us an overview were the team is working on. 

So the option to use shared teams fits the requirement, but we want to be able to assign more than one shared team to an issue
