text added to empty value in reference selector

Is it possible to assign a text (showing up in the selectable options) to the empty value of a reference selector? This in order to make the user aware that choosing for option "no choice" he explicitly chooses for this option. It would be very nice if, in addition, also can be chosen where this empty value (with caption) shows up, in other words, that the order of selectable items can be influenced.
