Register.php redirect to previous page?

[Ludnix]

I'm wondering if there is an option in vbulletin to have register.php redirect the user to their previous page on completion. I don't require email verification on my forum so it would be great if once they were registered it would take them to the original page the clicked the register link on rather than dumping them on the forum index.

I've seen a post about how to modify register.php to redirect somewhere else but I before I start changing register.php I thought I better make sure this isn't an option in the control panel or something.
