How to modify httpd.conf default settings

[Rémi ROUSSET]

Hello,
(Sorry for my english, because I'm french.)
When I create a new domain inplesk 8.3.0, the new domain is created whith a new httpd.conf.
In this conf file, the logformat is "plesklog".
I would like to find a solution to create all my new domains with the logformat "conbined".
How to do this ?

Thanks for your help.

Regards.
