Modifying User Notification Periods via CGI

Is there any way to modify a user’s notification period from the nagios cgi?

The case I have is that I am going on vacation and would like to toggle another nagios user to get notified and me not-notified. I have this user set up with the notification period of “never” and would like to toggle them to “24x7” via the CGI when my vacation starts. It would also be nice to do this should I ever get sick. I know I can do this via the shell and edit the config files, but I was just wondering if there was a way to do it from the CGI. If not, does anyone have any slick work-arounds for this?

Thanks!
