Changing names from directorys to individual and move them to other locations

[wiseguy]

Hallo,

Maybe its possible to change for example the directory from a customer (login name is mmueller) to this login name instead of client1.

The same with websites:
The user mmueller has a site named mueller.org and this is located in his directory /var/www/clients/client1/web1. Maybe its possible to change web1 to mueller.org

So what I want is to rename all users like I want:

/var/www/clients/client1/web1 -> /var/www/clients/mmueller/mueller.org

And I want to change it later: For example there is an other customer who wants to take the site mueller.org, his login name is amueller, and now I want to change the location from this web site as following:

/var/www/clients/mmueller/mueller.org -> /var/www/clients/amueller/mueller.org

Are this thinks possible? How can I change this in the ISPConfig3 Datebase so that I can use this behavior, if its not possible to do that with ISPConfig3?
