}

server {
    listen     192.168.1.2:10001;

It seems the lock lies in the fact there is no generic way for the
listen
directive to specify multiple ports, so you are stuck with that much
server
blocks.

Now, you could use the $server_port variable in the proxy_pass
directive,
but that brings no real improvement.

You could use configuration management tools to template configuration
generation, relieving you of the burden of maintaing all those blocks by
hand.
