You can bulk add or remove agents for multiple artists at once from your Agency Settings > Roster tab.
First, please select the Artists you would like to manage.
Use the Assign Agent or Assign Assistant buttons if you would like to add the same Agent/Assistant to the selected Artists.
Use the Add to bookings toggle if you would like the Agent to be always added to bookings, regardless of who creates the booking.
Use the Remove Agent/Assistant if you would like to remove a specific Agent/Assistant from the selected Artists.
