When a user is shared between multiple MIDs, and you go into MXisoagent to manage the team, when you click the "X" to delete the user, you should have a popup that asks you which account(s) they are to be deleted from. Maybe I want to delete them only from the account that I'm in, or maybe I want to delete them from multiple MIDs. Currently, when you delete them on one MID, they are deleted from all MID with which they are associated.
