In order to accomplish what you need, you can configure a dynamically configured mass virtual host.
To have it you should add something like the following to your httpd.conf file:
# get the server name from the Host: header
UseCanonicalName Off
# this log format can be split per-virtual-host based on the first field
LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog logs/access_log vcommon
# include the server name in the filenames used to satisfy requests
VirtualDocumentRoot /www/hosts/%0/docs
VirtualScriptAlias /www/hosts/%0/cgi-bin
That would do the same as the following:
NameVirtualHost 111.22.33.44
ServerName www.customer-1.com
DocumentRoot /www/hosts/www.customer-1.com/docs
ScriptAlias /cgi-bin/ /www/hosts/www.customer-1.com/cgi-bin
ServerName www.customer-2.com
DocumentRoot /www/hosts/www.customer-2.com/docs
ScriptAlias /cgi-bin/ /www/hosts/www.customer-2.com/cgi-bin
# blah blah blah
ServerName www.customer-N.com
DocumentRoot /www/hosts/www.customer-N.com/docs
ScriptAlias /cgi-bin/ /www/hosts/www.customer-N.com/cgi-bin
