How do I attach a public AND private reserved IP to a GCE instance?

Question

https://www.terraform.io/docs/providers/google/r/compute_instance.html

I want to reserve a external and internal IP but how do I attach both? I don't see examples in the TF docs.

It only has network_ip - (Optional) The *private* IP address ... https://www.terraform.io/docs/providers/google/r/compute_instance.html#network_interface

This is a working example within my compute instance module:

resource "google_compute_address" "internal" {
  name         = "${var.NAME}-int-ip"
  subnetwork   = "${var.SUBNETWORK}"
  address_type = "INTERNAL"
  address      = "${var.PRIVATE_IP}"
  region       = "${var.REGION}"
}

resource "google_compute_address" "external" {
  name         = "${var.NAME}-ext-ip"
  address_type = "EXTERNAL"
  region       = "${var.REGION}"
}

And then within the google_compute_instance resource block set the IP within the network_infrastructure block:

network_interface {
   network= "${var.NETWORK}"
   network_ip = "${google_compute_address.internal.address}"
   access_config {
      nat_ip = "${google_compute_address.external.address}" 
   }
