I have a new team member whom I'd like to add to an old assessment. How can I do that?

Once the assessment has ended and the report has been generated, you are no longer able to add additional team members. In fact, adding a new team member changes the dynamics of a team and may affect team members' perceptions. To get a complete and accurate picture of the new dynamics of the team, it would be necessary to have the whole team (with the new member) take the assessment again.
