Adding code to nginx config

Hello,

I need to add code to this location:
Add the code above inside the server section in the file, right before the php location block. Looks something like:
location ~ \.php$ {

Where is this location in ispConfig control panel ?

 

Maybe it would work if you add this nginx directive under WEBSITE --> OPTIONS --> NGINX DIRECTIVES.
For example, to mimic Apache's mod-rewrite (which is needed for Wordpress, Joomla and such) I simply add this code under above mentioned nginx directives:

Code:

location / {
                try_files $uri $uri/ /index.php?$args;
       }
