proxychains

Is it possible to switch the upstream proxy host without restarting the server? I'm currently using the anonymizeProxy helper like so:

const proxyChain = require('proxy-chain');

const user = '...';
const pass = '...';
const vpnHost = process.argv[2];
const oldProxyUrl = `http://${user}:${pass}@${vpnHost}:80`;
const newProxyUrl = proxyChain.anonymizeProxy(oldProxyUrl);

function 

It would be nice to have an optional parameter to change the path of the Maxmind DB. We have a paid license and a more accurate database than the GeoLite edition
