With a large organization, you may have members of your team that have the same roles and responsibilities.
For Example: You have 15 sales reps. They all have the same Roles/Responsibilities. So just create one seat and add each of their names to it!
How to do it
First, go to your Accountability Chart. There you will see the Add Person icon on any seat that is not the Visionary/Integrator.
Don't see the person you want to add as an option on the Accountability Chart? Add them to your People Directory!
