Can I configure the sort direction that is adopted when a column becomes the sorted column?

On the table here http://tablesorter.com/docs/, when I click Last Name's ^/v, I get a ^ sort. Fine.

When I then click First Name's ^/v and then Last Name's ^/v, I get a 'v' sort. How can I configure so that I again get an ^ sort? Leaving the used to click the current ^/v icon if he wants different.
