@riazmkhan I think I have a solution for you. the QAB have onItemClicked event which you can use for your case. You can add custom item with no address in it. Then to write a code that listens to onItemClicked event. When the event is fired you can check by code if the item that was clicked is the custom item. If so, you can query the dataset and fetch the address that you want according your roles and navigate the visitor to that address using navigate-to API
Hope that helps.
