Completion systems and methods to perform completion operations are disclosed. A completion system includes a tubular having a wall that defines a flowbore. The completion system also includes a first port disposed in the wall and configured to provide fluid communication between the flowbore and the annular region, and a communication path disposed at least partially within the wall and configured to provide fluid communication with an annulus of a well outside of the zone. The completion system further includes a second port disposed in the wall and configured to provide fluid communication between the flowbore and the communication path, a first diverter seat disposed in the flowbore uphole of the second port and configured to receive a diverter flowing through the flowbore; and a second diverter seat disposed in the flowbore uphole of the diverter seat and configurable to receive a second diverter flowing through the flowbore.
