Ability to add a person within the organization as a guest of a team.
My science center Data Management Team (DMT) uses Planner to track data releases through stages of the publication process. Each release has a task, each bucket is a stage of the process, checklist has work items to complete (including data and metadata reviews), reviewers are assigned to the task. Often reviewers are employees of the science center but not members of the DMT. We want to assign them to the Planner task without giving them edit/delete abilities (i.e. as a guest). However, guests are defined as persons outside the organization, so to assign the reviewer to a task we must add them as members of the DMT when in fact they are not. Recommend "Internal Guest" vs. "External Guest".
