If you have two entities, for example entity Building and entity Label

Make a reference set between your entities. Building *->* Label

Put the widget on your dataview of the Building and assign the "Label Object" and the "Caption Attribute" to use the Label entity. In the "Behaviour" you can allow to create objects etc.
