Under the clients in OpenERP(7) for the companies you have tab for all the contactpersons. How can I specify I only want to show the shipping addresses in this tab? I want to duplicate this group under the view, and have one tab for ALL the contacts and one tab for ONLY the shipping adresses.

Is this possible? Can someone explain how I can specify to use only the contacts of a specific type? I saw an attribute specified like e.g. : attrs="{'invisible': [('is_company','=',False)]}. This will hide all the companies. Is there a string like 'is_company' for something like 'is_shipping'??
