Reverse Date tag order

[SoundAdikt]

Hi, might be missing something here. Is there a way to reverse the order of the date tag so that it in the control point when I go into date, it lists dates starting with the newest first? I've incorporated date.onlyYear.index in tagoptions which works fine. Reading the user guide, it implies but + or - in front of date in indexTags will do what I need but this has no effect.

Many thanks.
