DVE: Node.Requires_Bus_Accesses in template

What I need is a list of "Requires_bus_access":

{% for access in Node.Requires_Bus_Accesses %}
  {{ access.name }} : requires bus access {{ access.bus_name }};
{% endfor %}

The access.name should be formed like this: deviceName_portName

And access.bus_name would be the same as the requires_bus_access value associated to the Device
