The Instance name tab enables you to set a name pattern for entity instances.
In order to create a name pattern you need to form a list of attributes and define a format string. Available attributes defined in this entity and its ancestors are listed in the Available attributes column.
In order to add an attribute to the list of attributes, select it in the list and move it to the Name pattern attributes column by clicking the right-arrow button. Similarly, to remove an attribute, select it in the right column and click the left-arrow button.
Studio automatically inserts the simplest format string in the Name pattern field, but you can edit it if needed.
By clicking the double-arrow button next to the field you can switch to the Source tab and see how the entity annotation appears in the code.
