enable php_value in htaccess

Hi all,

I have a server that use last virtualmin configs for httpd (FastCGI).
I have a customer that needs to activate auto_prepend_file and auto_append_file
How can I permit the activation using php_value in .htaccess for single domain/vhost?

Thanks

This is the vhost configuration:
