Global routes setting is not supported

[Witold Krecicki]

With this netplan yaml (which is stripped down example from man page):

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    id0:
      match:
        macaddress: 00:11:22:33:44:55
      addresses:
        - 192.168.14.2/24
      gateway4: 192.168.14.1
  routes:
   - to: 0.0.0.0/0
     via: 11.0.0.1
     metric: 3

netplan generate gives an error:
Error in network definition config.yaml line 1 column 2: unknown key routes

Also is not possible to set a multicast rote for an interface, only for ip.
something like:

routes:
 - to: 224.0.0.0/4
   dev: eth0
