I have this setup for my location directives

location /css/ {
proxy_pass http://127.0.0.1:8080/css/;
}

location /js/ {
proxy_pass http://127.0.0.1:8080/js/;
}

It seems a bit repetitive to me, is it possible to do something like this.

location /css/, /js/ {
proxy_pass http://127.0.0.1:8080/$1;
}

Where you can have one block process multiple locations, then the variable $1, copies the location defined into the proxy_pass URL? I might have about 10-20 and it would be easier to have one block then 20.
