@bobvandevijver let's make this customizable in generator.yml:

per builder basis:

```yaml
builders:
    list:
        params:
            templates: AcmeDemoBundle:User:list-templates.html.twig
    edit:
        params:
            templates: AcmeDemoBundle:User:edit-templates.html.twig
```

Or global (for all builders:


```yaml
params:
    templates: AcmeDemoBundle:User:templates.html.twig
```
