Unduplicating prox_pass in nginx location blocks

Question

I needed to IP block something in nginx and I ended up with duplicated proxy_forward code. How can I refactor and un-duplicate this?

server{
 location /admin{
 allow 123.90.250.0/24;
 allow 123.66.148.0/24;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Host $http_host;
 proxy_redirect off;
 proxy_pass http://foo;
 }
 location / {
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Host $http_host;
 proxy_redirect off;
 proxy_pass http://foo;
 }
}

You may move proxy settings to 'server' block. But proxy_pass should stay at 'location' block

upstream foo {
 server 127.0.0.1:8080;
}
server{
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Host $http_host;
 proxy_redirect off;
 location /admin {
 allow 123.90.250.0/24;
 allow 123.66.148.0/24;
 proxy_pass http://foo;
 }
 location / {
 proxy_pass http://foo;
 }
}
