The portlet is added in the theme like this: 

<@liferay_portlet["runtime"]  instanceId="portlet-id-12345" 
                        portletName="name-of-the-portlet" />

since the instance Id is hard coded in the theme , all the instances of the portlet has the same instance Id. Therefore, we can't add different portlet instance configurations on different pages. How to manage instance Id on embedded portlets so that it will be always same for a portlet instance but different on other pages.? Same behavior as of other portlets added directly on to the pages.
