Group multiple values on field display

Is there a way to limit the number of values displayed by a multi-value CCK field like you can in Views? Views, of course, has that wonderful little widget that says, "Group multiple values > If unchecked, each item in the field will create a new row, which may appear to cause duplicates. Show value(s) # starting from # (first item is 0)". I have a multi-value imagefield, and I just want to show the first image in a certain build mode. Is there a way to do this? If not, I'll make this a feature request.
