Seperate PHP error logs per domain,

Hello,

At present my server does not display errors but logs them to the 
error_log = "C:/zpanel/logs/php/php_errors.log" which i believe is default,
But all domain errors go onto the same log,

I wish to separate them per domain,
I tried to do via .htaccess but it throws 500 errors and kills the site,

It does work if i manually add a line into the httpd-vhosts.conf
php_value error_log "C:/zpanel/logs/php/<MYDOMAIN>_php.error.log"

But ofcorse this will be overwritten,

My question, is there a better way, or is it possible to have sentora write this line to conf when it generates the vhosts conf?


All files are fine to stay in the same directory, I am the only person who uses my server for multiple domains, and no one else,

Many thanks for your help in advance,

Cathelest.
