Forms Confirmation Options

In the Confirmation options for the Forms area a redirect page can be specified.  Is there any way to open this redirect page in a new window?

Hello,

 This is not possible trough the UI. I tried to force the redirect page to open with jQuery, but the problem is there is already onclick property that submits the form and the only option is to call window.open() in onclick as the submit button doesn`t support target="_blank" attribute.
