Dynamic IP in one and static in other networks with docker compose

What is correct syntax for dynamic address in one network and static in other network? (When container placed in 2 networks.)

Now my docker-compose.yml looks like this:

version: '2'
networks:
  default:
    driver: bridge
  vpn:
    driver: bridge
    ipam:
      config:
        - subnet: 10.1.2.0
services:
  openvpn:
    image: foo
    networks:
      - default
      - vpn
  app:
    image: bar
    networks:
      default:
        ipv4_address: 10.0.0.1/24
      vpn:
        ipv4_address: 10.1.2.3/24

It works, but I don't want to set ip addr in default network for app container to avoid conflicts.

Seems it is enough to just remove static IP address declaration:

  app:
    image: bar
    networks:
      default:
      vpn:
        ipv4_address: 10.1.2.3/24

In this case in default network dynamic address will be set, and in vpn static one.
