Using map directive for multiple virtual hosts

Hi,
   I have a requirement to rewrite incoming URL requests for multiple
virtual hosts, each with a unique (possibly overlapping) set of incoming
requests. We have each vhost in a server block, but since the map directive
lives in the http block I think that the behaviour we are currently seeing
is a result of having multiple map declarations not working - currently the
first virtual host with a configured map is working as expected, subsequent
maps are just returning the default. 

Each of our server directives, and it's associated map, are living in one
file per hostname. These files are included using a globbed include in the
main nginx.conf files http directive.

So the configuration looks something like this (these are abbreviated
examples with all the php processing stuff pulled out of it)

nginx.conf:
http {
  include       /etc/nginx/mime.types;
  default_type  application/octet-stream;

  access_log  /var/log/nginx/access.log;

  log_format  main  '$status $request';
  sendfile    on;

  server_tokens on;
  ...
  include /etc/nginx/our-sites/*;
}

/etc/nginx/our-sites/site1.com:
map $request_uri $new_uri_site1 {
	/store/product1 /store/new_products;
	/contact/us /contact/about;
	/services/consulting /contact/consulting;
}

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;
	ssl on;

	access_log  /var/log/nginx/site1.com.access-tls.log combined;
	error_log  /var/log/nginx/site1.com.error-tls.log;

	server_name site1.com;
	root /var/www/site1.com;
	index index.php;

	location / {
		try_files $uri $uri/ index.php?part=$uri&$args;
	}      
        ...
}


/etc/nginx/our-sites/site2.com:
map $request_uri $new_uri_site2 {
	/contact/us /contact/about;
	/services /contact/consulting;
	/people /staff/all;
}

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;
	ssl on;

	access_log  /var/log/nginx/site2.com.access-tls.log combined;
	error_log  /var/log/nginx/site2.com.error-tls.log;

	server_name site2.com;
	root /var/www/site2.com;
	index index.php;

	location / {
		try_files $uri $uri/ index.php?section=$uri;
	}      
        ...
}


Apart from moving the map directives inside each relevant server block as
rewrite rules does anyone know of a working solution for this situation?
