Say I want to name a a resource based on 2 variables so I have something like:

```

heat_template_version: 2013-05-23

description: Create network with

parameters:
  client_code:
    type: string
    description: 4 character customer code. Will be used for instance naming
  project_code:
    type: string
    description: 3 character project code

```

Now I would like to create resource with the name based on the client and project:

```

resources:
  test:
    type: OS::Neutron::Net
    properties:
      name: {get_param: client_code}{get_param: project_code}

```

That resource creation gives me a parse error. Is there anyway I can achieve this, or do I need to use a pre-script to generate my template?
