Product reference sort order

[bsdll]

In the backoffice you can set the sort option to product reference.

This works but means the "Sort by:" list on the category page starts off blank.

If you then pick an option you can not return in to reference order.

Is there a way to have reference on the list so that it doesn't start blank and can also be set back to that method?

If possible in a way that won't be overridden when doing an upgrade.
