Hi,
you should specify the Name pattern for the entity and after that this attribute will be displayed in the PickerField. To do so, open Entity Designer in Studio, go to the Instance name tab and select the property you want to display as a name. Select the attribute in the Available attributes list and move it to the Name pattern attributes list by clicking the button with the right arrow on it.
