Electronic – Best way to tell Altium that two pins are internally connected

altiumpcbpcb-design

So I'm making a shield for a Raspberry Pi, and as you all Know the GND pins are internally connected inside the Raspberry. How can I tell that to Altium, so that It don't asks me to route them?

Altium thinks that pins 6 and 9 are not connected, but they are. (Internally)

You should not do that. You should connect both pins to ground on the board. This reduces the impedance between the ground node of the Pi and the ground of the circuit, reducing ground bounce and the risk of "unintended operation".
