Template does not allow multiple mentions of the same interface (e.g. for adding additional addresses)

I configured the role like this based on hints from https://wiki.debian.org/NetworkConfiguration#Network_Interface_Names:

    network_interfaces_interfaces:
      - device: "{{ ansible_interfaces | select('match', '^en') | list | first }}"
        auto: true
        family: inet
        method: dhcp
      - device: "{{ ansible_interfaces | select('match', '^en') | list | first }}"
        auto: true
        family: inet
        method: static
        address: '192.168.178.4'

I'd expect an output like this:

# Ansible managed

auto enx001e06360900
iface enx001e06360900 inet dhcp

iface enx001e06360900 inet static
  address 192.168.178.4

Instead I got this (which destroys connectivity):

# Ansible managed

auto enx001e06360900
iface enx001e06360900 inet static
  address 192.168.178.4

Is this even possible? An interface being inet dhcp and inet static. Can you point me to an example?

[felixb]

Yes it is.
The first IP would be managed by DHCP and a second IP is attached statically.
