opcache disable for web domain in VestaCP

[Bez]

I have Apache 2.0 Handler with Zend OPcache.
To disable opcache we need just add to .htaccess file

Code: Select all

php_flag opcache.enable Off

I want do add new option on each web domain to switch opcache on/off.
What should I do to make new option for web domain settings like below?
