Install Wordpress WordPress subdirectory installation -> vhost already exists

Hi there,
I'm not sure if I can call this a bug or if it falls into an improvement request.

Since 123.09beta01 it is possible (LINK) to install WordPress into a subdirectory out of the box. This is a very handy functionality, but I think it could be improved.

Even though, the installation is domain.com/en/ the vhost and wp_updater uses domain.com (and maybe other things too?). So if I want to do a second wordpress installation at domain.com with subdirectory /deu/ for example, it fails because "vhost for domain.com already exists".

If in the installation, if subdirectory=true, it would add the subdirectory to all created files (for example: wp_updater_domain.com-deu and domain.com-deu.ssl.conf), it would be possible to easily create many blogs under one domain (I think the main use case is language sub-sites). The only thing the user had to do would be merge the nginx configs into one.

Just an idea

Best, JMX

PS: If you have an Idea how I can do the installation manually, please let me know. Currently I'm trying to backtrace everything that has been done for the first installation in /deu/ and replicate it for a manual installation into /en/.
