Redirect all except speciffic IP address

I'm developing a site for a client and want to redirect all visitors except me.

I know I can add a .htaccess file with the following redirect in it...

RewriteEngine On
RewriteBase /
RewriteCond %{REMOTE_HOST} !^22.22.22.22
RewriteRule .* http://place.toredirect.to [R=302,L]

Which will redirect everyone apart from a visitor with an IP address of 22.22.22.22

But can I do this via ISP Config without manually creating a .htaccess file?

 

It's in the apache options, in the last "tab" of your website, isn't it ?

 

Tried that with no luck.
