The promotion administrator now has the possibility of adding an internal reference to the promotion which allows substituting the title of the promotion as a reference in the control panel. Using this option, the administrators can organize their promotions in the control panel as they wish. 

You can add the internal reference from the management page of the promotion:

When added, the promotion will have its Title that you've added in the Editor of the promotion, and the internal reference that will be used to classify the promotion and organize it in the panel:

Note: The internal reference is not public. The promotion title is.
