Configure MaxBodySize for a proxy host ?

[isigmund]

I would need to change the client_max_body_size and enable the chunked_transfer_encoding for one of the proxy hosts that I configure through NPM. Is it possible to just add the following config entries simply in the advanced section of the proxy host to achieve this, or is there a different way to do this ?

client_max_body_size 0;
chunked_transfer_encoding on;
