Notification Email Shortcode?

Hello there,

Would there happen to be a Shortcode to change the "to" notification email? I've done a search on the forums, and tried finding the Shortcode documentation on the site but couldn't.

@Shonari,

No, I'm talking about [shortcodes] ... from within a Hook function, you can call Shortcodes. Either way, no matter how it's done, I need to be able to change the "to" notification from within my Hook function.

I'm calling the GravityForm this way:

$return .= "[gravityform id=3 title=false ajax=true to='mynewemail@gmail.com']";
    return $return;

It's being called within a $return variable because it's within another Hook.
