edit nph-build.cgi file

copy and make a second field sub _build_home and rename it to sub _build_second_home on the line in that field:

my $page = $CFG->{build_root_path} . "/" . $CFG->{build_index};

"/" this is where it builds the main home page just rename it to the directory you want it to build into

like this "/cars" or whatever way your directory is set up

then for the build fields add:

# Build Second Home Page.
GT::Plugins->dispatch ("$CFG->{admin_root_path}/Plugins", 'create_home', \&_build_second_home, {});

add that line below the:

# Build Home Page. field

thats it
