Implementation Artifact Override

[Steve Baillargeon]

Hi
Does ARIA support the ability to override an implementation artifact that is 
already been specified in the node type?
For instance:

node_types:
  aria.openstack.nodes.Server:
    derived_from: tosca.nodes.Compute
    ...
    interfaces:
      Standard:
        create:
          implementation: cloudify-openstack-plugin > nova_plugin.server.create


topology_template:
  node_templates:
    fortigate_vnf:
      type: aria.openstack.nodes.Server
      interfaces:
        Standard:
          create:
            implementation: my_script.py
