Bind multiple entities to single control

Hi experts,

I have a question about OData binding in sapui5.

How can I bind multiple entities to single control like the below snippet?

<sf:SmartField entitySet="Ent2" value="{prop2}" editable="{Ent1>prop1}"/>

I have no plan to use this situation yet, but I'm thinking about using switching properties of control if I can do this.

Best Regards,
