Upvoting this. The current setup of Additional Team Members defeats the purpose of Teams. If a user is assigned to multiple teams, they should be able to be treated as full team members. We have 6 branches (or Teams in HubSpot) but we have some salespeople who work at multiple branches. They should be able to be looped into round-robin meeting assignments, automation, workflow rotation, etc. just like a primary member of that team. This is a crucial function that we need for our business.
