how to pre-config subdomain-path ?

[Leyton4114-2]

Hi @all,
since PSA 11.x subdomains will no more created in /var/www/vhosts/domain.tld/subdomains.

All users are able to change the new path in the old one, but how i can pre-config the path for using subdomains for all users, so their must not change it herself ?
