How to update just the [Types] section via fcgiconfig.js

Hi All,

How do I just add a new entry to the [Types] section in the fcgiext.ini via the fcgiconfig.js

I want to have multiple sites use the same [php529] section.
php:SITEID00=php529
php:SITEID01=php529
php:SITEID02=php529

How do I do this from the command fcgiconfig.js

Cheers
Adam
